2 Peter 2:12

Rather than behaving as good angels do, the false teachers would act like animals. They would follow their lower instincts, their natural desires, instead of their reasons. Animals live mainly by instinct. Peter believed the false teachers deserved treatment similar to animals therefore. The last clause involves a play on words in Greek. The idea is that they will perish as beasts, like so much meat (cf. Judges 10). Peter did not mean they would escape eternal condemnation.

"As animals are trapped through their eagerness to satisfy their appetite, so self-indulgence betrays these men to their ruin." [Note: W. H. Bennett, "The General Epistles, James, Peter, John, and Jude," in The Century Bible: A Modern Commentary, p. 274.]
