These are wells without water, clouds driven by a storm, for whom the blackness of darkness has been reserved forever. For, 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; promising them liberty, while they themselves are bondservants of corruption; for a man is brought into bondage by whoever overcomes him. For 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. For 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. But 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.”

Solomon @solomon · Proverbs 26:7-11

Like the legs of the lame that hang loose, so is a parable in the mouth of fools. As one who binds a stone in a sling, so is he who gives honor to a fool. Like a thorn bush that goes into the hand of a drunkard, so is a parable in the mouth of fools. As an archer who wounds all, so is he who hires a fool or he who hires those who pass by. As a dog that returns to his vomit, so is a fool who repeats his folly.
