Note 1 topic: figures-of-speech / activepassive

ἄχρι τελεσθῇ τὰ χίλια ἔτη

until ˓may_be˒_finished (Some words not found in SR-GNT: καί ἔβαλεν αὐτόν εἰς τήν Ἄβυσσον καί ἔκλεισεν καί ἐσφράγισεν ἐπάνω αὐτοῦ ἵνα μή πλανήσῃ ἔτι τά ἔθνη ἄχρι τελεσθῇ τά χιλία ἔτη μετά ταῦτα δεῖ αὐτόν λυθῆναι μικρόν χρόνον)

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: [until the thousand years had ended]

Note 2 topic: figures-of-speech / activepassive

δεῖ αὐτὸν λυθῆναι

˱it˲_˓is˒_fitting (Some words not found in SR-GNT: καί ἔβαλεν αὐτόν εἰς τήν Ἄβυσσον καί ἔκλεισεν καί ἐσφράγισεν ἐπάνω αὐτοῦ ἵνα μή πλανήσῃ ἔτι τά ἔθνη ἄχρι τελεσθῇ τά χιλία ἔτη μετά ταῦτα δεῖ αὐτόν λυθῆναι μικρόν χρόνον)

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. If you need to say who will do the action, the context suggests that it may be the angel who has “the key to the abyss,” as [20:1](../20/01.md) describes. Alternate translation: [God will command the angel to release him]
