2 Peter 2:21-22

New Matthew Bible

²¹ For it would have been better for them not to have known the way of righteousness than, after they have known it, to turn from the holy commandment given to them. ²² It has happened to them according to the true proverb: The dog is turned to his vomit again, and the sow that was washed, to her wallowing in the mire.
