Matthew 15:11-18

11Not that which entereth into the mouth defileth the man; but that which proceedeth out of the mouth, this defileth the man. 12Then came the 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. And if the blind guide the blind, both shall fall into a pit. 15And Peter answered and said unto him, Declare unto us the parable. 16And he said, Are ye also even yet without understanding? 17Perceive ye not, that whatsoever goeth into the mouth passeth into the belly, and is cast out into the draught? 18But the things which proceed out of the mouth come forth out of the heart; and they defile the man.
