OET interlinear PHM 1:17

uW Translation Notes:

Note 1 topic: grammar-connect-condition-fact

εἰ & με ἔχεις κοινωνόν

if & (Some words not found in SR-GNT: εἰ Οὖν μέ ἔχεις κοινωνόν προσλαβοῦ αὐτόν ὡς ἐμέ)

Paul is writing in a way that makes it seem as though it is possible that Philemon does not consider that Paul is his partner, but he knows that Philemon does consider Paul to be his partner. This is a way of getting Philemon to agree on one thing (that Paul is a partner) so that he will agree to the other thing (to receive Onesimus). If your language does not state something as uncertain if it is certain or true, and if your readers might think that what Paul is saying is not certain, then you could translate his words as an affirmative statement. Alternate translation: [since you have me as a partner]

Note 2 topic: grammar-connect-logic-result

οὖν

(Some words not found in SR-GNT: εἰ Οὖν μέ ἔχεις κοινωνόν προσλαβοῦ αὐτόν ὡς ἐμέ)

Therefore means that what came before this word is the reason for what comes after it. It may be that Paul intends for everything that came before to be the reason, because this word also indicates that Paul is now coming to the main point of the letter. Use a natural method in your language to indicate this transition. Alternate translation: [Because of all of these things]

Note 3 topic: figures-of-speech / ellipsis

προσλαβοῦ αὐτὸν ὡς ἐμέ.

receive (Some words not found in SR-GNT: εἰ Οὖν μέ ἔχεις κοινωνόν προσλαβοῦ αὐτόν ὡς ἐμέ)

Paul is leaving out some of the words here that a sentence would need in many languages to be complete. If it would be helpful in your language, you could supply these words from the context. Alternate translation: [receive him just as you would receive me]
