Matthew 15:16 ASV

¹⁴  Let them alone: they are blind guides. And if the blind guide the blind, both shall fall into a pit.

¹⁵  And Peter answered and said unto him, Declare unto us the parable.

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.
