Berean Study Bible (BSB) - Revelation 20:3 >

And he threw him into the Abyss, shut it, and sealed it over him, so that he could not deceive the nations until the thousand years were complete. After that, he must be released for a brief period of time.

Textus Receptus (TR) - Revelation 20:3 >

καὶ ἔβαλεν αὐτὸν εἰς τὴν ἄβυσσον, καὶ ἔκλεισεν αὐτόν, καὶ ἐσφράγισεν ἐπάνω αὐτοῦ, ἵνα μὴ πλανήσῃ τὰ ἔθνη ἔτι, ἄχρι τελεσθῇ τὰ χίλια ἔτη· καὶ μετὰ ταῦτα δεῖ αὐτὸν λυθῆναι μικρὸν χρόνον.
