Matthew 12:34-37

Offspring of vipers! How are you able to say good things when you are evil? For from the abundance of the heart the mouth speaks. The good person from his good treasury brings out good things, and the evil person from his evil treasury brings out evil things. But I tell you that every worthless word that they speak, people will give an account for it on the day of judgment! For by your words you will be vindicated, and by your words you will be condemned.”
