OET interlinear YHN (JHN) 12:42

uW Translation Notes:

Note 1 topic: figures-of-speech / explicit

τῶν ἀρχόντων

˱of˲_the rulers

Here, rulers refers to the Jewish religious leadership, specifically the Jewish council called the Sanhedrin, which made decisions about Jewish law. (See: council) See how you translated rulers in [3:1](../03/01.md). Alternate translation: [the members of the Jewish ruling council]

Note 2 topic: figures-of-speech / activepassive

ἵνα μὴ ἀποσυνάγωγοι γένωνται

in_order_that (Some words not found in SR-GNT: Ὅμως μέντοι καί ἐκ τῶν ἀρχόντων πολλοί ἐπίστευσαν εἰς αὐτόν ἀλλά διά τούς Φαρισαίους οὐχ ὡμολόγουν ἵνα μή ἀποσυνάγωγοι γένωνται)

If your language does not use the passive form in this way, you could express the idea in active form or in another way that is natural in your language. Alternate translation: [so that the Pharisees would not ban them from the synagogue]

Note 3 topic: figures-of-speech / metaphor

μὴ ἀποσυνάγωγοι γένωνται

(Some words not found in SR-GNT: Ὅμως μέντοι καί ἐκ τῶν ἀρχόντων πολλοί ἐπίστευσαν εἰς αὐτόν ἀλλά διά τούς Φαρισαίους οὐχ ὡμολόγουν ἵνα μή ἀποσυνάγωγοι γένωνται)

John uses put out of the synagogue to refer to no longer being allowed to go into the synagogue and no longer belonging to the group of people who attended services at the synagogue. When people were put out of the synagogue, they were shunned by their local community. If this might confuse your readers, you could express the meaning plainly. Alternate translation: [they would not be allowed to enter the synagogue] or [they would no longer belong to the synagogue community]
