Matthew 15:13-17

But he answered and said, Every plant, which my heavenly Father hath not planted, shall be rooted up.

Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.

Then answered Peter and said unto him, Declare unto us this parable.

And Jesus said, Are ye also yet without understanding?

Do not ye yet understand, that whatsoever entereth in at the mouth goeth into the belly, and is cast out into the draught?
