Genesis 6:12
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ εἶδεν κύριος ὁ θεὸς τὴν γῆν καὶ ἦν κατεφθαρμένη ὅτι κατέφθειρεν πᾶσα σὰρξ τὴν ὁδὸν αὐτοῦ ἐπὶ τῆς γῆς
And God looked upon the earth and saw that it was corrupt; for all living creatures (note: Literally all flesh; similarly in verses 13, 17, and 19) on the earth had corrupted their ways.
