Proverbs 26:3-7

A whip for the horse, a bridle for the donkey, and a rod for the backs of fools! Do not answer a fool according to his folly, or you yourself will be just like him. Answer a fool according to his folly, or he will be wise in his own eyes. Sending a message by the hands of a fool is like cutting off one’s feet or drinking poison. Like the useless legs of one who is lame is a proverb in the mouth of a fool.
