2 Peter 2:19-22

Haweis(i) 19 Preaching liberty to them, while they themselves are the slaves of corruption: for by whatever a man is overcome, by that also he is enslaved. 20 For if having escaped from the defilements of the world by the knowledge of our Lord and Saviour Jesus Christ, they are again enveloped by them and overcome, their last deeds are worse than the first. 21 For it had been better for them never to have been acquainted with the way of righteousness, than, after knowing it, to have turned aside from the holy commandment delivered unto them. 22 But the true proverb is verified in them, The dog hath returned to his own vomit; and the sow which was washed to its wallowing in the mire.
