2 Peter 2:12-14

2:12 But these men, like irrational animals – creatures of instinct, born to be caught and destroyed – do not understand whom they are insulting, and consequently in their destruction they will be destroyed, 2:13 suffering harm as the wages for their harmful ways. By considering it a pleasure to carouse in broad daylight, they are stains and blemishes, indulging in their deceitful pleasures when they feast together with you. 2:14 Their eyes, full of adultery, never stop sinning; they entice unstable people. They have trained their hearts for greed, these cursed children!

2 Peter 2:22

2:22 They are illustrations of this true proverb: “A dog returns to its own vomit,” and “A sow, after washing herself, wallows in the mire.”
