Matthew 15:13

9And they worship me in vain, teaching as doctrine rules made by men.’”

10He summoned the multitude, and said to them, “Hear, and understand.

11That which enters into the mouth doesn’t defile the man; but that which proceeds out of the mouth, this defiles the man.”

13But he answered, “Every plant which my heavenly Father didn’t plant will be uprooted.

14Leave them alone. They are blind guides of the blind. If the blind guide the blind, both will fall into a pit.”

15Peter answered him, “Explain the parable to us.”

16So Jesus said, “Do you also still not understand?

17Don’t you understand that whatever goes into the mouth passes into the belly and then out of the body?
