Matthew 15:19

17 Do not ye yet 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.

For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:

20 These are the things which defile a man: but to eat with unwashen hands defileth not a man.

21 Then Jesus went thence, and departed into the coasts of Tyre and Sidon.

Do read the surrounding verses too, because the context often says more than a single verse.
