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