2 Peter 2:21-22

World English Bible

²¹ For it would be better for them not to have known the way of righteousness, than after knowing it, to turn back from the holy commandment delivered to them. ²² But it has happened to them according to the true proverb, “The dog turns to his own vomit again,”Proverbs 26:11 and “the sow that has washed to wallowing in the mire.”
