JMNT(i)
66 From out of this [saying, or, circumstance], therefore, many from out of His [group] of disciples went away into the things back behind (or: went off to the rear) and then were no longer continuing to walk about (or: travel around; = make a way of life) with Him.
67 Then Jesus says to the twelve, "You men are not also wanting (or: intending) to be going away (or: to progressively withdraw), are you?" (or: “Don’t you men want to leave, too?”)
68 Then Simon Peter decidedly gave answer to Him, "O Lord (Master; Owner), toward whom shall we proceed to go away? You continue holding (or: constantly have; habitually hold [out]) gush-effects of eonian Life (sayings and declarations of life whose source and origin are the Age [of Messiah]; results of the flows of things spoken pertaining to life of and for the ages)!
69 – and we ourselves have trusted and are now convinced so as to now be believing, and we by personal, intimate experience have come to know that You Yourself ARE (or: continuously exist being) God’s Holy One (or: the Sacred One from God; the Set-apart One which is God)."
70 Jesus considered and gave answer to them, "Do I Myself not select and pick you out – the twelve – for Myself (or: Did I not choose you twelve Myself)? And one from among you men is a person who thrusts things through [people] (or: a devil)!"
71 Now, He was speaking of Judah (or: Judas), [son] of Simon Iscariot, for this one – one from out of [other MSS: being a part of] the twelve – was about to proceed handing Him over.
