18For, uttering great swelling words of emptiness, they entice in the lusts of the flesh, by licentiousness, those who are indeed escaping from those who live in error;
19promising them liberty, while they themselves are bondservants of corruption; for a man is brought into bondage by whoever overcomes him.
20For if, after they have escaped the defilement of the world through the knowledge of the Lord and Savior Jesus Christ, they are again entangled in it and overcome, the last state has become worse for them than the first.
21For it would be better for them not to have known the way of righteousness, than, after knowing it, to turn back from the holy commandment delivered to them.
22But it has happened to them according to the true proverb, “The dog turns to his own vomit again,” and “the sow that has washed to wallowing in the mire.”
