Revelation 12:3
Nestle 1904 Greek New Testament · Berean Standard Bible
Καὶ ὤφθη ἄλλο σημεῖον ἐν τῷ οὐρανῷ καὶ ἰδοὺ δράκων πυρρός μέγας ἔχων κεφαλὰς ἑπτὰ καὶ κέρατα δέκα καὶ ἐπὶ τὰς κεφαλὰς αὐτοῦ ἑπτὰ διαδήματα
Then another sign appeared in heaven: a huge red dragon with seven heads, ten horns, and seven royal crowns on his heads.
