Matthew 15:18 (KJV)

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?

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

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

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

And, behold, a woman of Canaan came out of the same coasts, and cried unto him, saying, Have mercy on me, O Lord, thou son of David; my daughter is grievously vexed with a devil.

But he answered her not a word. And his disciples came and besought him, saying, Send her away; for she crieth after us.
