Matthew 15:17 - 20
Do not ye yet understand, that whatsoever entereth in at the mouth goeth into the belly, and
is cast out into the draught?
But those things which proceed out of the mouth come forth from the heart; and they defile
For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false
These are the things which defile a man: but to eat with unwashen hands defileth not a man.
