Proverbs 26:9-12

As a thorn that goeth up into the hand of a drunkard, So is a parable in the mouth of fools. As an archer that woundeth all, So is he that hireth a fool and he that hireth them that pass by. As a dog that returneth to his vomit, So is a fool that repeateth his folly. Seest thou a man wise in his own conceit? There is more hope of a fool than of him.
