2 Peter 2:20-22

ABU(i) 20 For if, having escaped the pollutions of the world through the knowledge of the Lord and Savior Jesus Christy but having again become entangled therein they are overcome, the last state is become worse with them than the first. 21 For it were better for them not to have known the way of righteousness, than, having known it, to turn back from the holy commandment delivered to them. 22 But it has happened to them according to the true proverb: A dog, returned to his own vomit; and, A sow that was washed, to the wallowing in the mire.
