Revelation 17:11
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Καὶ τὸ θηρίον ὃ ἦν, καὶ οὐκ ἔστιν, καὶ αὐτὸς ὄγδοός ἐστιν, καὶ ἐκ τῶν ἑπτά ἐστιν, καὶ εἰς ἀπώλειαν ὑπάγει.
The beast that was, and now is not, is an eighth king, who belongs to the other seven and is going into destruction.
