2 Peter 2:20-22

VIN(i) 20 For if, after they have escaped the defilements of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled by them, and overcome, they are worse off in the end than at the beginning. 21 It would have been better for them not to have known the way of righteousness than to know it and turn their backs on the holy commandment that was committed to them. 22 Of them the proverbs are true: “A dog returns to its vomit,” and, “A sow that is washed goes back to her wallowing in the mud.”
