These men, however, slander what they do not understand, and like irrational animals, they will be destroyed by the things they do instinctively.
KJV
But these speak evil of those things which they know not: but what they know naturally, as brute beasts, in those things they corrupt themselves.
ASV
But these rail at whatsoever things they know not: and what they understand naturally, like the creatures without reason, in these things are they destroyed.
