JMNT(i)
50 "this is (or: continuously exists being) the Bread which is repeatedly (or: constantly) stepping down from out of the atmosphere (or: progressively descending from heaven) to the end that ANYONE may eat from out of It and not die (or: he can, or would, not die; [B reads: and he can continue not dying]).
51 "I Myself am (or: continuously exist being) the continuously living Bread – the One stepping down (or: descending) from out of the midst of the atmosphere (or: heaven). If anyone should eat from out of this Bread, he will continue living on into the Age. Now the Bread, also, which I Myself will continue giving over (or: for the sake of) the life of the world (the ordered system; or: = ‘the totality of human social existence’ – Walter Wink; the aggregate of humanity) is (or: continuously exists being) My flesh!"
52 Therefore, the Jews (= religious authorities) began violently arguing (disputing; warring [with words]) toward one another, constantly saying, "How is this one presently able to give us his flesh to eat?"
53 Then Jesus said to them, "Most truly (Amen, amen) I am now laying out the arrangement for (or: saying to) you people: unless you folks should at some point eat the flesh of the Son of the Human (the Son of man; = the eschatological messianic figure), and then would drink His blood (or: since you would not eat the flesh which is the Human Being, and further, drink His blood), you are continuing not holding (or: habitually having or presently possessing) Life within yourselves!
54 "The person habitually eating (continuously chewing or masticating) My flesh and drinking My blood is continuously possessing (habitually holding; progressively having) eonian Life (life derived from and having the qualities of the Age; age-enduring and eon-lasting life), and I Myself will proceed raising, resurrecting and standing him back up again in the Last Day (or: for and by the last Day),
55 "for My flesh is (or: constantly exists being) true (real; genuine) food, and My blood is (or: continuously exists being) true (real; genuine) drink.
56 "The person habitually eating (constantly chewing [on]) My flesh and repeatedly drinking My blood is continuously remaining (abiding; dwelling) within, and in union with, Me – and I Myself within, and in union with, him.
57 "Just as (or: In corresponding accordance as) the continuously-living Father sent Me off (or: forth) as an Emissary (commissions Me as a Representative and sends Me on a mission), and I, Myself, am continuously living through (or: because of) the Father, likewise he who is habitually eating (repeatedly chewing and feeding [on]) Me, that person will also continue living, through (or: because of; by means of) Me.
58 "This is (or: continuously exists being) the Bread: the One stepping down (or: descending) from out of the midst of heaven (or: [the] sky and atmosphere) – not according as the fathers ate and died. The person habitually eating (continually chewing and feeding [on]) this Bread will continue living [p66 & others read middle: will in (or: of) himself continue living; D reads present: is continuously living] on into the Age."
