2 Peter 2:20-22

BSB(i) 20 If indeed they have escaped the corruption of the world through the knowledge of our Lord and Savior Jesus Christ, only to be entangled and overcome by it again, their final condition is worse than it was at first. 21 It would have been better for them not to have known the way of righteousness than to have known it and then to turn away from the holy commandment passed on 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.”
