2 Peter 2:20-22.
For if after that they have escaped the pollutions of the world, through the knowledge of the Lord and Savior Jesus Christ, they are again entangled therein, and overcome; the latter end is worse with them than the beginning. For it had been better for them not to have known the way of righteousness, than after they have known it, to turn from the holy commandment delivered unto them. But it is happened unto 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.
