OET interlinear REV 7:13

uW Translation Notes:

Note 1 topic: figures-of-speech / hendiadys

ἀπεκρίθη & λέγων μοι

answered & saying (Some words not found in SR-GNT: Καί ἀπεκρίθη εἱς ἐκ τῶν πρεσβυτέρων λέγων μοί Οὗτοι οἱ περιβεβλημένοι τάς στολάς τάς λευκάς τίνες εἰσίν καί πόθεν ἦλθον)

This phrase expresses a single idea by using two words connected with and. The word responded indicates that this elder was saying these things to John in response to what John was seeing in this vision. If it would be more natural in your language, you could express this meaning with an equivalent phrase that does not use “and.” Alternate translation: [asked me]

Note 2 topic: figures-of-speech / rquestion

οὗτοι, οἱ περιβεβλημένοι τὰς στολὰς τὰς λευκὰς, τίνες εἰσὶν καὶ πόθεν ἦλθον

(Some words not found in SR-GNT: Καί ἀπεκρίθη εἱς ἐκ τῶν πρεσβυτέρων λέγων μοί Οὗτοι οἱ περιβεβλημένοι τάς στολάς τάς λευκάς τίνες εἰσίν καί πόθεν ἦλθον)

This elder is using the question form to introduce something he wants to make sure John understands. Since John answers the question in the next verse, it would be appropriate to retain the question form in your translation, but if it would be helpful to your readers, you could word the question in a way that would show its purpose. Alternate translation: [Do you know who these people are who are wearing white robes and where they have come from]

Note 3 topic: figures-of-speech / activepassive

περιβεβλημένοι τὰς στολὰς τὰς λευκὰς

˓having_been˒_clothed (Some words not found in SR-GNT: Καί ἀπεκρίθη εἱς ἐκ τῶν πρεσβυτέρων λέγων μοί Οὗτοι οἱ περιβεβλημένοι τάς στολάς τάς λευκάς τίνες εἰσίν καί πόθεν ἦλθον)

If your language does not use this passive form, you could express the idea in active form or in another way that is natural in your language. Alternate translation: [the ones wearing white robes]
