JMNT(i)
11 And so, indeed on the one hand, every priest has stood daily, publicly serving and offering the same sacrifices many times (or: often) – which things not even once (never) are able or have power to take away sins (failures; errors) which surround (which envelop) [us].
12 Yet on the other hand this One, after at one point offering one sacrifice – stretched for the whole length – over [the situation of] sins (or: on behalf of failures and errors), sat within the right [part or side] of God (or: at the right [hand] of God; centered in God's [place of power, honor and acceptance]) on into the whole length (or: extended into the unbroken continuance),
13 continuously, one after another, taking hold with the hand to embrace and welcome from out of the rest (the remaining and leftover) until the hated ones that belong to Him (His enemies; the ruiners that He has; folks who are hostile in relation to Him) can be placed [as] a footstool of His feet (= would be set in a humble and supportive position in relation to His body).
14 For you see, by and in one offering He has perfected (brought to the goal; matured; completed; finished; brought to their purposed destiny) – on into the whole length (or: extended or stretched into the unbroken continuance) – those folks being one after another set-apart (separated; made sacred and holy; [p46 reads: restored back up again into the original state and condition; rescued back and delivered again; made healthy and whole again]).
15 Now the set-apart Breath-effect (or: Holy Spirit; Sacred Attitude) is also habitually witnessing (or: progressively attesting; periodically testifying) to us, for us, in us and by us, for after His having before said,
16 "This [is] the arrangement (covenant; disposition) which I will continue arranging (covenanting; disposing) toward them after those days," the Lord [= Yahweh] says, "Continuously giving My laws upon their hearts, I will even progressively write them upon their mental perception (or: comprehension; that which passes through the mind), [Jer. 31:33]
17 "and I will by no means still continue having called to mind [other MSS: in no way would I at any point still be reminded of] their failures (sins; errors; misses of the target) and of their lawlessnesses (unlawful behaviors)." [Jer. 31:34]
18 So (or: But; Now) where [there is] a sending away (a release; forgiveness and a causing to flow away) of these things, [there is] no longer an offering concerning sin (failure)!
