A good man out of the good treasure of his heart brings forth good; and an evil man out of the evil treasure of his heart brings forth evil. For out of the abundance of the heart his mouth speaks.
Matthew 15:17-20 NKJV[17]
Do you not yet understand that whatever enters the mouth goes into the stomach and is eliminated? [18] But those things which proceed out of the mouth come from the heart, and they defile a man. [19] For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies. [20] These are the things which defile a man, but to eat with unwashed hands does not defile a man.”
