JMNT(i)
19 Why, then, the Law [= Torah] of The Transgressions? It was at one point set aiming at, and thus provided a view to, grace and favor [D, F, G & others read: It was appointed for (or: set {beside}) grace] (or: Why, then, the Law? It was placed close and applied {imposed; added} on behalf of the walks to the side of [the path]; or: What, therefore [is] the Law [= Torah]? Something set, as a favor, face-to-face with the over-steppings and transgressions to the side of and beyond [the Way]) – being precisely arranged and thoroughly prescribed and mandated by injunction through means of agents (or: messengers; folks with the message) within the midst of [the] hand of a mediator (or: in an umpire's hand; within [the] hand of an arbitrator or an intermediary in a middle position) – as far as to where (or: until which place or time) the Seed would (or: should) come, to Whom and for Whom the promise had been made (or: in Whom He had been promised).
20 Now there is no mediator of one (= when one person is concerned or is acting alone). Yet (or: Now) God is One. [note: to make a promise, one is sufficient – there is no need for a middleman]
21 Is the Law, then, following the pattern of (or: down from; or: down against; or: on a par with; commensurate with; corresponding to) God's promises? May it not happen (It could not come to be; = Of course not)! For if a law (or: [the] Law) were given which continued having power or being able at any point to make alive (to construct or create living folks; to engender living ones; to impart life), really, the fairness and equity in right relationship (the rightwised qualities of justice and freedom from guilt within the Way pointed out; also = covenant inclusion) were likely being from out of the midst of [the] Law [= Torah; other MSS: residing within law].
22 But to the contrary, the Scripture encircles and encloses [as fish in a net] all things, shuts them up together and locks the whole (the totality of everything) under (or: by) failure (error; deviation; the missing of the target; sin), to the end that the Promise would (or: could) suddenly be given to (or: in; for) the folks habitually trusting (or: progressively believing with faith's conviction) from out of Jesus Christ's faith (or: forth from the midst of the faith whose source and origin is Jesus Christ; from the midst of the trust and conviction which is Jesus Christ; or: so that the promise [which comes] forth from Jesus Christ’s trust, can at some point be given to the people presently having convinced assurance).
23 So before the [time, or, event for] the Faith to come (or: prior to the coming of this trust, assurance and conviction), we were being continuously confined and held in custody under the watch of a guard, being folks constantly encircled, enclosed, shut up and locked together by and under Law, [with a view to, aimed and moving] into the Faith and Trust being about to be unveiled (or: revealed; disclosed),
24 so that, consequently, the Law (= Torah) had come to be (had been birthed into existence) and continued being our supervising guardian and attending escort [with a view to, aimed and moving] into Christ, to the end that we could (or: would) be made just, fair and equitable (rightwised; turned in the right direction and placed in right relationship within the Way pointed out; freed from guilt; also = included in covenant) from out of faith, conviction and trust.
25 So now with the coming of the Faith and Trust, we no longer continuously exist (or: are) under [the] supervising guardian or an attending escort [comment: = the Law; Torah]!
