2 Peter 2:21-22

21st Century King James Version

²¹ For it would have been better for them not to have known the way of righteousness, than, after they had known it, to turn from the holy commandment delivered unto them.

²² But it has happened unto them according to the true proverb: “The dog turns to his own vomit again,” and, “the sow that was washed, to her wallowing in the mire.”
