Matthew 15:16-22

16And Jesus said, Are ye also yet without understanding? 17Do not ye yet understand, that whatsoever entereth in at the mouth goeth into the belly, and is cast out into the draught? 18But those things which proceed out of the mouth come forth from the heart; and they defile the man. 19For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies: 20These are the things which defile a man: but to eat with unwashen hands defileth not a man.

21Then Jesus went thence, and departed into the coasts of Tyre and Sidon. 22And, behold, a woman of Canaan came out of the same coasts, and cried unto him, saying, Have mercy on me, O Lord, thou Son of David; my daughter is grievously vexed with a devil.
