Parallel
Jude 1:10
Nestle 1904 Greek New Testament · Berean Standard Bible
οὗτοι δὲ ὅσα μὲν οὐκ οἴδασιν βλασφημοῦσιν ὅσα δὲ φυσικῶς ὡς τὰ ἄλογα ζῷα ἐπίστανται ἐν τούτοις φθείρονται
These men, however, slander what they do not understand, and like irrational animals, they will be destroyed by the things they do instinctively.
