JMNT(i)
12 And thus (or: Consequently) the Law [= the Torah], indeed, [is] set-apart (holy; sacred; consecrated) and the implanted goal (impartation of the finished product within; inward directive; commandment) [is] set-apart (holy; sacred) and in accord with the Way pointed out (fair; equitable; just; = related to covenant) and good (virtuous).
13 Then did the good come to be death for me (in me; to me)? Certainly not (may it not come to be)! But rather, the Sin (failure; error; the miss; the mistake; the deviation) – to the end that sin (failure; error; etc.) may be brought to light and made visible (or: in order that it may be made to appear and be shown as being sin) – is constantly producing (or: working down) death through the good [i.e., the commandment], to the end that the Sin (failure; the miss; error; the deviation), through the implanted goal (impartation of the finished product within; inward directive; commandment), may come to be in accord with a throwing-beyond that is missing the target (or: may happen according to excess which is failing; may become extremely erroneous; should come to be in line with a deviating shooting over the goal; or, substantively: may become an exceeding failure, and excessive sinner or a total outcast).
14 For you see, we have seen and are aware (or: on the one hand I recognize and know) that the Law (= Torah; or: law; custom; principle) constantly exists being spiritual (is pertaining to spirit; is having the qualities of a Breath-effect; is relating to attitude), yet (or: on the other hand) I [= Israel? or, Adam] myself am (or: exist being) fleshly (composed of flesh; carnal; flesh-oriented; or: = affected by the alienated self), being one having been and now remaining sold under [the power and control of] the Sin (under failure and the miss of the Target [of Torah?]).
