14 Let them alone: they are blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.
15 Then answered Peter and said unto him, Declare unto us this parable.
16 And Jesus said,
17 Do you not yet understand, that whatsoever enters in at the mouth goes into the belly, and is cast out into the drain?
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 These are the things which defile a man: but to eat with unwashed hands defiles not a man.
