'Brute' in the Bible

For brute nature under all its forms--beasts and birds, reptiles and fishes--can be subjected and kept in subjection by human nature.

But these, as natural brute beasts, made to be taken and destroyed, speak evil of the things that they understand not; and shall utterly perish in their own corruption;

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.
