2 Peter 2:20–22

For if, after they have escaped the defilements of the world through the knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and overcome, the last state has become worse for them than the first. For it would have been better for them never to have known the way of righteousness than after knowing it to turn back from the holy commandment delivered to them. What the true proverb says has happened to them: “The dog returns to its own vomit, and the sow, after washing herself, returns to wallow in the mire.”

If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and are overcome, they are worse off at the end than they were at the beginning. It would have been better for them not to have known the way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them. Of them the proverbs are true: “A dog returns to its vomit,” and, “A sow that is washed returns to her wallowing in the mud.”

For if, having escaped the world’s impurity through the knowledge of the Lord and Savior Jesus Christ, they are again entangled in these things and defeated, the last state is worse for them than the first. For it would have been better for them not to have known the way of righteousness than, after knowing it, to turn back from the holy command delivered to them. It has happened to them according to the true proverb: A dog returns to its own vomit, and, “A washed sow returns to wallowing in the mud.”

For if, after they have escaped from the defilements of the world through the knowledge of the Lord and Savior Jesus Christ, and they are again entangled in these things and succumb to them, the last state has become worse for them than the first. For it would have been better for them not to have known the way of righteousness than having known it, to turn back from the holy commandment that had been delivered to them. The statement of the true proverb has happened to them, “A dog returns to its own vomit,” and “A sow, after washing herself, returns to wallowing in the mud.”

For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour 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 own vomit again; and the sow that was washed to her wallowing in the mire.
