Matthew 15:18 “But the things that proceed out of the mouth come from the heart, and those defile the man.
Matthew 12:33 “Either make the tree good and its fruit good, or make the tree bad and its fruit bad; for the tree is known by its fruit. 34 “You brood of vipers, how can you, being evil, speak what is good? For the mouth speaks out of that which fills the heart. 35 “The good man brings out of his good treasure what is good; and the evil man brings out of his evil treasure what is evil. 36 “But I tell you that every careless word that people speak, they shall give an accounting for it in the day of judgment. 37 “For by your words you will be justified, and by your words you will be condemned.”
