OET interlinear ACTs 1:21

uW Translation Notes:

Note 1 topic: translate-versebridge

To help your readers understand Peter’s main point in this verse and the next one, you could combine both verses into a verse bridge. You could put his main point in a first sentence and his further explanation in a second sentence. Alternate translation: [Therefore it is necessary for someone else to become a witness with us of Jesus’ resurrection. It should be one of the men who accompanied us during all the time that the Lord Jesus came in and went out among us, beginning from the baptism of John until the day that he was taken up from us.]

Note 2 topic: figures-of-speech / exclusive

ἡμῖν & ἡμᾶς

˱with˲_us & (Some words not found in SR-GNT: δεῖ Οὖν τῶν συνελθόντων ἡμῖν ἀνδρῶν ἐν παντί χρόνῳ ᾧ εἰσῆλθεν καί ἐξῆλθεν ἐφʼ ἡμάς ὁ Κύριος Ἰησοῦς)

In the first instance of us, Peter means himself and his fellow apostles, not everyone to whom he is speaking, so use the exclusive form of the word if your language marks that distinction. However, in the second instance of us, Peter could well mean himself and his entire audience, so use the inclusive form in that instance.

Note 3 topic: figures-of-speech / idiom

εἰσῆλθεν καὶ ἐξῆλθεν ἐφ’ ἡμᾶς ὁ Κύριος Ἰησοῦς

came_in (Some words not found in SR-GNT: δεῖ Οὖν τῶν συνελθόντων ἡμῖν ἀνδρῶν ἐν παντί χρόνῳ ᾧ εἰσῆλθεν καί ἐξῆλθεν ἐφʼ ἡμάς ὁ Κύριος Ἰησοῦς)

Peter is speaking in an idiomatic way. Alternate translation: [the Lord Jesus lived among us]
