Matthew 15:10-20
10And he called to him the multitude, and said unto them, Hear, and understand: 11Not that which entereth into the mouth defileth the man; but that which proceedeth out of the mouth, this defileth the man. 12Then came his disciples, and said unto him, Knowest thou that the Pharisees were offended, when they heard this saying? 13But he answered and said, Every plant which my heavenly Father planted not, shall be rooted up. 14Let them alone: they are blind guides of the blind. And if the blind guide the blind, both shall fall into a pit. 15And Peter answered and said unto him, Declare unto us this parable. 16And Jesus said, Are ye also even yet without understanding? 17Do ye not yet perceive, that whatsoever goeth into the mouth passeth into the belly, and is cast out into the draft? 18But the things which proceed out of the mouth come forth out of the heart; and they defile the man. 19For out of the heart come forth evil thoughts, murders, adulteries, fornications, thefts, false witness, railings: 20these are the things which defile the man; but to eat with unwashed hands defileth not the man.
