JMNT(i)
47 Consequently, the chief (or: ranking) priests and the Pharisees gathered [the] Sanhedrin (= convoked a council of the leaders of the Jewish religious and political culture), and they began to say, "What are we presently doing, seeing that this man is repeatedly doing many signs?
48 "If we let him go on in this way (or: If we disregard him in this manner; or: Suppose we thus abandon, neglect or leave him alone), they will all progressively put trust (will continue believing) into him, the Romans will proceed to come, and they will progressively take away both our place and our nation (= political station, culture and corporate ethnic identity)."
49 Yet one of them, Caiaphas, being chief priest of that year, said to them, "You people have not seen, nor perceived, nor know anything,
50 "neither are you logically reasoning or taking into account the fact that he is progressively bringing it together for you (or: it is advantageously bringing things together for you), so that one man can die over (or: to the end that one person should and would die away for the sake of [in the sense of "instead of"]) the People, and not [that] the whole nation should destroy itself!"
51 Now, he did not say this from himself, but to the contrary, being chief priest of that year, he prophesied that Jesus was being about to be dying away over [the situation of] (or: for the sake of) the Nation (or: ethnic group),
52 and not over [the condition of] the Nation (or: on behalf of the ethnic group) only, but further, to the end that He could gather God's children together – those having been thoroughly scattered – into one (or: so that He would lead together into unity God’s divided, dissipated and disintegrated born-ones that have been dispersed throughout).
53 Therefore, from that day they deliberated and consulted together to the end that they should kill Him.
