Verse 12.— But these, as natural brute beasts. These wicked ones, here being described, act as if they were irrational like the beasts that are destined to be slaughtered as food for men. So great, indeed, are their irrational and senseless actions that they speak evil of, and in opposition to, things which they do not understand. Utterly perish in their own corruption. Nothing can be plainer as to the end of such characters. Their destruction is full and complete.
