Matthew 15:11; Matthew 15:18; Matthew 15:20

11 Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.

18 But those things which proceed out of the mouth come forth from the heart; and they defile the man.

20 These are the things which defile a man: but to eat with unwashen hands defileth not a man.
