Revelation 13:18
Nestle 1904 Greek New Testament · Berean Standard Bible
Ὧδε ἡ σοφία ἐστίν ὁ ἔχων νοῦν ψηφισάτω τὸν ἀριθμὸν τοῦ θηρίου ἀριθμὸς γὰρ ἀνθρώπου ἐστίν καὶ ὁ ἀριθμὸς αὐτοῦ ἑξακόσιοι ἑξήκοντα ἕξ
Here is a call for wisdom: Let the one who has insight calculate the number of the beast, for it is the number of a man, and that number is 666.
