Matthew 15:18 ASV

¹⁶  And he said, Are ye also even yet without understanding?

¹⁷  Perceive ye not, that whatsoever goeth into the mouth passeth into the belly, and is cast out into the draught?

¹⁸  But the things which proceed out of the mouth come forth out of the heart; and they defile the man.

¹⁹  For out of the heart come forth evil thoughts, murders, adulteries, fornications, thefts, false witness, railings:

²⁰  these are the things which defile the man; but to eat with unwashen hands defileth not the man.
