Revelation 17:12
Nestle 1904 Greek New Testament · Berean Standard Bible
καὶ τὰ δέκα κέρατα ἃ εἶδες δέκα βασιλεῖς εἰσιν οἵτινες βασιλείαν οὔπω ἔλαβον ἀλλὰ ἐξουσίαν ὡς βασιλεῖς μίαν ὥραν λαμβάνουσιν μετὰ τοῦ θηρίου
The ten horns you saw are ten kings who have not yet received a kingdom, but will receive one hour of authority as kings along with the beast.
