For our freedom Christ has us set free.¹ Jesus promised this freedom from slavery to sin: I will ask the Father, and he will give you another Helper, to be with you forever, even the Spirit of truth²…the Holy Spirit, whom the Father will send in my name, he will teach you all things and bring to your remembrance all that I have said to you.³ I will not leave you as orphans; I will come to you.⁴ If anyone loves me, he will keep my word, and my Father will love him, and we will come to him and make our home with him.⁵ [T]herefore you stand firm and cannot entangle yourselves in a yoke of slavery again.⁶

Why? The fruit (ὁ καρπὸς) or “result” of this freedom—which is God the Father, God the Son, God the Holy Spirit taking up residence within us—is (Galatians 5:22b, 23 ESV):

…love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law [Table].

One who experiences his love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control like a spring of water welling up to eternal life,⁷ recognizes the source of this fruit (result). The Spirit’s result is mine only in that sense that he who is joined to the Lord becomes one spirit with him.⁸ This is why Jesus could promise (Matthew 5:48 EXP8):

You will be perfect, therefore, as your heavenly Father is perfect [Table].

I quoted the EXP1 translation of Galatians 5:1 above because I choose to understand the verb στήκετε, a form of στήκω, in the indicative mood (EXP1: you stand firm) rather than as an imperative (ESV: stand firm).⁹ Either is permissible according to the Koine Greek Lexicon online, but the indicative mood jibes better with the freedom for which Christ has us set free. And I am working out [my] own salvation with fear and trembling, for it is God who works in [me], both to will and to work for his good pleasure [Table].¹⁰ But why was it even necessary to quote the EXP8 translation of Matthew 5:48?

According to the Koine Greek Lexicon online the verb ἔσεσθε, a form of εἰμί, is in the future tense and indicative mood (EXP8: will be) rather than the imperative mood (ESV: must be). But the ESV translation is (Matthew 5:48 ESV):

You therefore must be perfect, as your heavenly Father is perfect [Table].

According to Arthur Carr in Volume 1 of the Cambridge Greek Testament for Schools and Colleges Commentary online, there is still a choice to make here:

ἔσεσθε τέλειοι. Lit. ‘ye shall be perfect.’ Either (1) in reference to a future state, ‘if ye have this true love or charity ye shall be perfect hereafter’; or (2) the future has an imperative force, and τέλειοι is limited by the preceding words = perfect in respect of love, i.e. ‘love your enemies as well as your neighbours,’ because your Father being perfect in respect of love does this. This use of the future is in accordance with the Hebrew idiom.¹¹

With a bit of decoding I favor option (1): “if ye have this true love or charity ye shall be perfect hereafter.” You have this love or charity—But the fruit of the Spirit is love¹²—supplied by God through his indwelling Holy Spirit to all who believe Jesus. This love—his own love (as opposed to some emotion I try to conjure out of gratitude)—is the fulfilling of the law.¹³ You (ὑμεῖς) will be (ἔσεσθε) perfect (τέλειοι, a form of the adjective τέλειος): “mature, complete, perfect, full-grown; morally perfect; impeccable, faultless in beliefs and practice; maximum, utter” (Ephesians 1-3; cf. 3:19).

When? when the Lord brings you to the place of recognizing who you are in Christ: the new self, created after the likeness of God in true righteousness and holiness.¹⁴ I have been crucified with Christ, Paul described God’s salvation, and it is no longer I who live, but Christ lives in me. (But he who is joined to the Lord becomes one spirit with him.¹⁵) So the life I now live in the body, I live because of the faithfulness of the Son of God, who loved me and gave himself for me,¹⁶ on the cross, yes, but beyond the cross and forever (εἰς τὸν αἰῶνα).

As Jesus prayed to his Father (John 17:20-23 ESV):

I do not ask for these only, but also for those who will believe¹⁷ in me through their word, that they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me [Table]. The glory that you have given me I¹⁸ have given to them, that they may be one even as we are¹⁹ one, I in them and you in me, that they may become perfectly one, so²⁰ that the world may know that you sent me and loved them even as you loved me.

The Greek word translated perfectly above was τετελειωμένοι, a middle/passive participle of the verb τελειόω: “to die; to be perfect; to be consecrated to; to be initiated into.”

In the past a statement like—“This use of the future is in accordance with the Hebrew idiom”²¹—might have hypnotized me into compliance with option (2).

[T]he future has an imperative force, and τέλειοι is limited by the preceding words = perfect in respect of love, i.e. ‘love your enemies as well as your neighbours,’ because your Father being perfect in respect of love does this.²²

But Jesus continues to draw me to Himself. Since I began to understand that He (as a human child) learned what He taught (as an adult) from the Holy Spirit’s instruction in the Old Testament Scriptures, and that He expected the teacher of Israel to understand the Scriptures as He did, I’ve become much more critical of this kind of nonspecific assertion. And so I ask: Is the “Hebrew idiom” that seeks to transform a Greek verb in the indicative mood (e.g., a statement of fact) into an imperative (e.g., “a command or instruction given to the hearer, charging the hearer to carry out or perform a certain action”²³) simply because it is in the future tense, a “Hebrew idiom” as God the Father and Holy Spirit intended and as Jesus understood it? Or is that “Hebrew idiom” the understanding of those in Israel who pursued a law that would lead to righteousness [but] did not succeed in reaching that law? [Table]. Why? [Why did they not succeed in reaching that law?] Paul asked rhetorically, and then answered: Because they did not pursue it by faith, but as if it were based on works [Table].²⁴

A few words about the Cambridge Greek Testament for Schools and Colleges Commentary seem to be in order. In the introduction to Matthew’s Gospel the Preface by the General Editor states: “THE General Editor of The Cambridge Bible for Schools thinks it right to say that he does not hold himself responsible either for the interpretation of particular passages which the Editors of the several Books have adopted, or for any opinion on points of doctrine that they may have expressed.” In the Editor’s Preface which follows that of the General Editor—dated December 21, 1880—Arthur Carr listed the lexicons, grammars and various “works principally consulted,” and he acknowledged “several friends who have helped me with suggestions.” The Cambridge Greek Testament for Schools and Colleges Commentary appears to be a collection of the works of individual authors who were described, and described themselves, as editors.

Since the translators of the ESV seem to have gone with option (2), and in lieu of an answer to my question about that “Hebrew idiom” from the late Mr. Carr, I’ll consider the ESV translations of the other occurrences of ἔσεσθε in the New Testament.

And when you pray, you must not be like the hypocrites. For they love to stand and pray in the synagogues and at the street corners, that they may be seen by others. Truly, I say to you, they have received their reward.²⁵

The phrase you must not be was οὐκ ἔσεσθε in the critical text (NET parallel Greek and NA²⁸) or ουκ εση in the received text (Stephanus Textus Receptus and Byzantine Majority Text). Both ἔσεσθε and εση are forms of the verb εἰμί in the future tense and indicative mood: “you will not be.” The former is a 2^nd person plural verb; the latter is a 2^nd person singular verb. Mr. Carr explained:

προσεύχησθε οὐκ ἔσεσθε, instead of the singular προσεύχῃ οὐκ ἔσῃ, the singular introduced to harmonise with context ὅταν ποίῃς Matthew 6:2, ὅταν προσεύχῃ Matthew 6:6.

Mr. Carr revealed his preference²⁶ for the originality of the critical text by stating that “the singular [was] introduced [later] to harmonise with context.” (The factual content of this assertion is based presumably on the dating of extant manuscripts.) Likewise, the translators of the ESV reveal at least an affinity for the idea that “the future [tense] has an imperative force”²⁷ by rendering “you will not be” (οὐκ ἔσεσθε or οὐκ ἔσῃ) you must not be.

Mr. Carr did not reiterate the two options he presented for understanding ἔσεσθε in Matthew 5:48. He did, however, present further evidence of his preference for the critical text as he hinted that ἔσεσθε created a rule:

5. προσεύχησθε [e.g., προσεύχησθε in Matthew 6:5 rather than the singular προσευχή]. Plural, because here the reference is to public worship. It is a rule for the Church.

So Mr. Carr’s claim, that Καὶ ὅταν προσεύχησθε οὐκ ἔσεσθε ὡς οἱ ὑποκριταί “is a rule for the Church,” seems supported by the ESV translators: And when you pray, you must not be like the hypocrites.²⁸ The Greek words translated the hypocrites were οἱ ὑποκριταί, a form of ὑποκριτής: “hypocrite, pretender, impious person.” According to the Merriam-Webster Dictionary online, however, these are all relatively late meanings of the Greek word:

A number of different things might pop to mind when we hear the word hypocrite. Maybe it’s a politician caught in a scandal; maybe it’s a religious leader doing something counter to their creed; maybe it’s a scheming and conniving character featured in soap operas. But it’s likely that the one thing that doesn’t come to mind is the theater.

The word hypocrite ultimately came into English from the Greek word hypokrites, which means “an actor” or “a stage player.” The Greek word itself is a compound noun: it’s made up of two Greek words that literally translate as “an interpreter from underneath.” That bizarre compound makes more sense when you know that the actors in ancient Greek theater wore large masks to mark which character they were playing, and so they interpreted the story from underneath their masks.

The Greek word took on an extended meaning to refer to any person who was wearing a figurative mask and pretending to be someone or something they were not. This sense was taken into medieval French and then into English, where it showed up with its earlier spelling, ypocrite, in 13th-century religious texts to refer to someone who pretends to be morally good or pious in order to deceive others. (Hypocrite gained its initial h- by the 16th century.)

It took a surprisingly long time for hypocrite to gain its more general meaning that we use today: “a person who acts in contradiction to his or her stated beliefs or feelings.” Our first citations for this use are from the early 1700s, nearly 500 years after hypocrite first stepped onto English’s stage.

Strong’s Concordance still referenced the original meaning: “lit: a stage-player.” But even Strong’s offered meanings for this word that probably didn’t exist for a thousand or more years from the time Jesus spoke, or Matthew recorded, it. Be that as it may, translating an indicative verb ἔσεσθε as if it were an imperative has a dulling effect on Jesus’ commands (Matthew 6:6 ESV):

But when you pray, go into your room and shut the door and pray to your Father who is in secret. And your Father who sees in secret will reward you [Table].

Here, the Greek word translated go into actually is a verb in the imperative mood: εἴσελθε, a form of εἰσέρχομαι. It is completely acceptable to translate εἴσελθε go into; it still means you must go into: “a command or instruction given to the hearer, charging the hearer to carry out or perform a certain action”²⁹ Contrasted to you must not be like the hypocrites, however, go into may not quite convey how dramatic a gesture Jesus commanded. “When you pray, you must go into” (not the synagogue of actors nor street corners where actors pray, but into) your room and shut the door and pray to your Father who is in secret.

The Greek word translated will reward in the next clause was ἀποδώσει, a form of ἀποδίδωμι in the future tense and indicative mood, another word like ἔσεσθε, though not translated, “And your Father who sees in secret must reward you.” Neither did Mr. Carr offer “must reward” as another option to will reward. He was more preoccupied with other matters:

ταμεῖον has high authority (אBDE) for ταμιεῖον; cp. the late form ὑγεία for ὑγίεια.

6. ταμιεῖον. A private oratory or place of prayer. These were usually in the upper part of the house; in classical Greek ‘storehouse’ or ‘treasury’, the meaning of the word Luke 12:24. See Matthew 24:26.

Πρόσευξαι τῷ πατρί σου τῷ ἐν τῷ κρυπτῷ. Christ was the first to enjoin clearly secret and silent prayer. Certainly to pray aloud and in public appears to have been the Jewish practice (see however 1 Samuel 1:13); it is still the practice with the heathen and Mahommedans. The Roman looked with suspicion on private prayer: ‘quod scire hominem nolunt deo narrant’³⁰ (Seneca). Cp. Hor. Ep. I. 16. 59–62, where see Macleane’s note. Cp. also Soph. Electra 638, where Clytemnestra apologises for offering up a secret prayer.³¹

Here, again, I favor option (1), to treat the indicative mood like the indicative mood, a statement of fact, a promise to Jesus’ hearers/followers. It is true in their near future that Jesus’ hearers/followers will not be like the actors who love to stand and pray in the synagogues and at the street corners, that they may be seen by others,³² because Jesus’ hearers/followers will be actors who obey his commands instead: [you must] go into your room and shut the door and [you must] pray to your Father who is in secret.³³ And Jesus’ promise will be true in their not too distant future because his hearers/followers will cease to be actors, portraying a certain character by obeying rules, to actually be those who are joined to the Lord [and become] one spirit with him.³⁴

They will be crucified with Christ. It [will] no longer [be they] who live, but Christ who lives in [them]. And the life [they will then] live in the flesh [they will] live by faith in the Son of God, who loved [them] and gave himself for [them]. [They will] not nullify the grace of God, for if righteousness were through the law, then Christ died for no purpose.³⁵ They will be those who do what is true [who come] to the light, so that it may be clearly seen that [their] works have been carried out in God.³⁶ They will be those who are released from the law, having died to that which held [them] captive, so that [they] serve in the new way of the Spirit and not in the old way of the written code.³⁷

(This prompts me to wonder how a “Church” governed by “a rule”—you must not be like the hypocrites—relates to the ἐκκλησία of God in Jesus Christ. It sounds as if this “Church,” rather than being free to serve in the new way of the Spirit, is consigned instead to serve in the old way of [a new] written code.)

I’ve lumped the next four occurrences of ἔσεσθε together because of their similarities, but none was translated as an imperative in the ESV (Matthew 10:21, 22; 24:9; Mark 13:13; Luke 21:17).

Brother will deliver brother over to death, and the father his child, and children will rise against parents and have them put to death, and you will be (ἔσεσθε) hated by all for my name’s sake. But the one who endures to the end will be saved.

Then they will deliver you up to tribulation and put you to death, and you will be (ἔσεσθε) hated by all nations for my name’s sake.

And you will be (ἔσεσθε) hated by all for my name’s sake. But the one who endures to the end will be saved.

You will be (ἔσεσθε) hated by all for my name’s sake.

The only author of the Cambridge Commentary to mention ἔσεσθε specifically in his notes on these verses was Alfred Plummer, Volume 3, in his comments to Mark 13:13.

καὶ ἔσεσθε μισούμενοι. Verbatim the same in all three. The analytical fut. marks the hatred as a process continually going on…

I might ask whether the continuity of this hatred owes more to the present participle μισούμενοι, a form of μισέω in the middle/passive voice: “to hate, despise, detest (esp. to persecute); to strongly dislike; to refuse to have any further interest in.” Surely, the breadth of meaning of μισούμενοι lends credence to the factual content of Jesus’ statement (ἔσεσθε) in the indicative mood well into any humanly foreseeable future. At any rate, Mr. Plummer asserted no “imperative force” for the future tense here: “you must be hated.”

Jesus’ promise that his hearers/followers will be sons of God follows (Luke 6:35 ESV):

But love your enemies, and do good, and lend, expecting nothing in return, and your reward will be great, and you will be (ἔσεσθε) sons of the Most High, for he is kind to the ungrateful and the evil [Table].

Though I may be tempted in isolation like this to think that Jesus held up my works—loving my enemies, doing good, lending, expecting nothing in return—as the cause which effected my becoming a son of the Most High, the rest of Scripture and my own life assure me that I am one of the ungrateful and evil people who has benefited from his kindness.

Here, again, I understand the truth of ἔσεσθε in Jesus’ hearers’/followers’ near future as a demonstration of faith. As they put on the character of God like actors obeying Jesus’ commands, He receives their act as faith in his word. And in their not too distant future—after Jesus’ death, resurrection, ascension and the giving of his Holy Spirit—their reward will be (ἔσται, a singular form of εἰμί in the future tense and indicative mood) great: They will be born from above, not of blood nor of the will of the flesh nor of the will of man, but of God.³⁸ And they will love with his love, do good by his goodness, be kind through his kindness, for the fruit [result] of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law [Table].³⁹

F. W. Farrar, the author of Volume 4 of the Cambridge Commentary didn’t mention an imperative option for ἔσεσθε (or any other verb in the future tense and indicative mood) here (e.g., “you must be sons of the most high,” or “your reward must be great”). He simply reiterated the phrase in Greek with an instruction to compare it to Sirach.

Aside from the differences of number, the most notable difference is the word ὡς in Sirach: “Deliver him that suffereth wrong from the hand of the oppressor; and be not fainthearted when thou sittest in judgment. Be as a father unto the fatherless, and instead of an husband unto their mother: so shalt thou be as [ὡς] the son of the most High, and he shall love thee more than thy mother doth.”⁴⁰ This is the work of an actor. By doing xyz the actor becomes as or like the character he or she portrays.

But the Son of the Most High said: love your enemies, and do good, and lend, expecting nothing in return, and your reward will be great, and you will be sons of the Most High, for he is kind to the ungrateful and the evil.⁴¹ Here, again, the works are those of an actor until the promise is fulfilled, but the promise—you will be (ἔσεσθε) sons of the Most High—is not something an actor’s works can achieve. The actor’s works are received by the Most High as a demonstration of the actor’s faith in the Son of the Most High. The fulfillment of the promise—you will be (ἔσεσθε) sons of the Most High—is the work of God. As Jesus prayed: that they may be one even as we are one, I in them and you in me, that they may become perfectly one, so that the world may know that you sent me and loved them even as you loved me.⁴²

The next occurrence is a direct reference to the freedom in Christ which is the overarching theme of these essays (John 8:36 ESV):

So if the Son sets you free, you will be (ἔσεσθε) free indeed.

Alfred Plummer, the author of Volume 5 of the Cambridge Commentary asserted no “imperative force” to the future tense in John 8:36: “you must be free indeed.” He made no direct reference to ἔσεσθε at all here:

ἐὰν οὖν ὁ υἱός. As before, any son is meant. ‘If the son emancipates you, your freedom is secured; for he is always on the spot to see that the emancipation is carried out.’ The statement is general, but with special reference to the Son of God, who frees men by granting them a share in His Sonship. If they will abide in His word (John 8:31), He will abide in them (John 6:56), and will take care that the bondage from which He has freed them is not thrust upon them again.

This insight seems particularly interesting in the light of For our freedom Christ has us set free; therefore you stand firm and cannot entangle yourselves in a yoke of slavery again.⁴³ Mr. Plummer continued by highlighting the adverb ὄντως (ESV: indeed):

ὄντως. Here only in S. John: comp. Luke 23:47; Luke 24:34; 1 Timothy 5:3; 1 Timothy 5:5; 1 Timothy 5:16. It expresses reality as opposed to appearance; ἀληθῶς (John 8:31; John 4:42; John 6:14; John 7:40) implies that this reality is known.⁴⁴

The next occurrence of ἔσεσθε is found in Jesus’ promise of the Holy Spirit’s power to perform the works of God through those who are one spirit with Him (Acts 1:8 ESV).

But you will receive⁴⁵ power when the Holy Spirit has come upon you, and you will be (ἔσεσθε) my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth [Table].

The Greek word translated you will receive was λήμψεσθε, a form of the verb λαμβάνω in the future tense and indicative mood, but J. R. Lumby, the author of Volume 6 of the Cambridge Commentary, didn’t offer an option (2) for interpreting either λήμψεσθε or ἔσεσθε in the imperative mood (e.g., “you must receive,” or “you must be”) because “the future has an imperative force.”⁴⁶

The next occurrence of ἔσεσθε is found in Paul’s instruction about speech (1 Corinthians 14:9 ESV):

So with yourselves, if with your tongue you utter speech that is not intelligible, how will anyone know what is said? For you will be (ἔσεσθε) speaking into the air.

The note addressing ἔσεσθε by J. J. Lias in Volume 8 of the Cambridge Commentary reads:

ἔσεσθε … λαλοῦντες. Not precisely equivalent to λαλήσετε. The condition of the persons rather than the nature of the action is indicated, ‘Ye shall be as men who are speaking into (or unto) the air.’

Frankly, the “condition of the persons” is a more interesting insight to consider in Matthew 5:48 and 6:5 than transforming “a statement of fact” into “a command or instruction given to the hearer, charging the hearer to carry out or perform a certain action”⁴⁷ For our freedom Christ has us set free; therefore you stand firm and cannot entangle yourselves in a yoke of slavery again.⁴⁸

The next occurrence of ἔσεσθε is in Paul’s paraphrase of some Old Testament promises (2 Corinthians 6:18 ESV).

and I will be a father to you, and you shall be (ἔσεσθε) sons and daughters to me, says the Lord Almighty.

Some tables comparing the Greek of Paul’s paraphrase to that of the Septuagint can be found in Christianity, Part 2. The Greek word translated I will be was ἔσομαι, a 1^st person singular form of the verb εἰμί. Like ἔσεσθε, ἔσομαι is in the future tense and indicative mood. Here again, Alfred Plummer, the author of Volume 9 of the Cambridge Commentary, didn’t offer an option (2) for interpreting either ἔσομαι or ἔσεσθε in the imperative mood (e.g., “I must be,” or “you must be”). Mr. Plummer did offer a plausible explanation for Paul’s addition to the Old Testament text: καὶ θυγατέρας, and daughters (ESV).

The recognition of daughters of God as well as sons of God is found in Isaiah 43:6 : but it was the Gospel which first raised woman to her true position in God’s family. At Corinth, where the degradation of women in the name of religion was so conspicuous, it might be specially necessary to point out that women are God’s daughters. Comp. Acts 2:17-18 from Joel 2:28.

The final occurrence of ἔσεσθε is found in Peter’s quotation from Leviticus (1 Peter 1:16 ESV):

since it is written, “You shall be⁴⁹ (ἔσεσθε) holy, for I am holy.”

The received text (Stephanus Textus Receptus and Byzantine Majority Text) had γενεσθε (KJV: Be ye) here (rather than ἔσεσθε), a form of the verb γίνομαι in the 2nd aorist tense and imperative mood: “a command or instruction given to the hearer, charging the hearer to carry out or perform a certain action.” G. W. Blenkin, the author of Volume 18 of the Cambridge Commentary, favoring apparently the critical text even as he retained the flavor of the received text, wrote:

Generally in the N.T. the title ἅγιος describes the Christian’s privilege, as one whom God has “set apart” for Himself, rather than the Christian’s character. But such consecration to God demands a corresponding character, and here St Peter emphasizes that demand by quoting the standard laid down in the “Law of Holiness,” “Ye shall be holy, for I am holy,” Leviticus 11:44-45; Leviticus 19:2. In the former passage the words are connected with things which were to be regarded as clean or unclean, but in the latter they are connected with various moral laws.

I’ve quoted some English translations of these verses from Leviticus from both the Hebrew of the Masoretic text and the Greek of the Septuagint in three tables below.

The Hebrew word וְהִתְקַדִּשְׁתֶּם֙ (qāḏaš) was translated sanctify yourselves therefore (Tanakh), and you are to sanctify yourselves (NET) and, Consecrate yourselves therefore (ESV) from the Masoretic text. The Tanakh on chabad.org rendered it and you shall sanctify yourselves, which is interesting since it captures some sense of promise. The rabbis who translated the Septuagint chose καὶ ἁγιασθήσεσθε, a passive form of ἁγιάζω in the future tense and indicative mood, a promise to you from the Lord your God: and you shall be sanctified (NETS), and ye shall be sanctified (English Elpenor).

The Hebrew וִֽהְיִיתֶ֣ם (hāyâ) followed by קְדשִׁ֔ים (qāḏôš) was translated and be ye holy (Tanakh), and be holy (NET, ESV) from the Masoretic text, the result apparently of sanctifying oneself. In the Septuagint, however, this was clearly another promise to you from the Lord your God: καὶ ἅγιοι ἔσεσθε, and you shall be holy (NETS), and ye shall be holy (English Elpenor).

This time, the Hebrew, וִֽהְיִיתֶ֣ם (hāyâ) followed by קְדשִׁ֔ים (qāḏôš), was translated ye shall therefore be holy (Tanakh), You shall therefore be holy (ESV) from the Masoretic text, wafting a scent of promise, rather than the more consistently imperative and you are to be holy (NET). But again, in the Septuagint καὶ ἔσεσθε ἅγιοι, you shall be holy (NETS) and ye shall be holy (English Elpenor), is unequivocally a promise to you from the Lord your God, the result of his own holiness.

Here the Hebrew of the Masoretic text, קְדשִׁ֣ים (qāḏôš) followed by תִּֽהְי֑וּ (hāyâ), was translated as a promise, Ye shall be holy (Tanakh), You shall be holy (ESV), except for You must be holy (NET). And again, the Greek translation of the Septuagint was ἅγιοι ἔσεσθε, You shall be holy (NETS), Ye shall be holy (English Elpenor), a promise to you from the Lord your God.

A note (60) in the NET on Matthew 5:48—So then, be perfect, as your heavenly Father is perfect—reads:

This remark echoes OT statements in Lev 11:44-45 and Lev 19:2: “you must be holy as I am holy.”

I’ll continue to quote the EXP8 translation of Matthew 5:48—You will be perfect, therefore, as your heavenly Father is perfect [Table]—Arthur Carr’s contention that “the future has an imperative force”⁵⁰ notwithstanding. The mere possibility that περιπατεῖτε in the phrase πνεύματι περιπατεῖτε was intended to be understood as a statement of fact (“by the spirit you walk”) rather than as “a command or instruction…charging the hearer to carry out or perform a certain action”⁵¹ (“by the spirit you must walk”) has revolutionized my walk these past two months. Everyday since, that little faith has made it so much easier to put on the new self, created after the likeness of God in true righteousness and holiness.⁵²

What marvelous wonders will faith in Jesus’ promise of perfection bring?

A table of the occurrences of ἔσεσθε in the ESV and the corresponding entries from the Cambridge Greek Testament for Schools and Colleges Commentary follows.

According to the note in the Cambridge Greek Testament for Schools and Colleges Commentary Peter referenced Leviticus 11:44, 45 and Leviticus 19:2, and according to a note (34) in the NET, Peter quoted from Leviticus 19:2 in 1 Peter 1:16. Tables comparing the Greek of that quotation with that of the Septuagint follow.

Tables comparing Leviticus 11:44; 11:45 and 19:2 in the Tanakh, KJV and NET, and tables comparing the Greek of Leviticus 11:44; 11:45 and 19:2 in the Septuagint (BLB and Elpenor), and tables comparing 1 Peter 1:16; John 17:20 and 17:22, 23 in the KJV and NET follow.
