Matthew 15:15

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

12Then the disciples came and said to him, “Do you know that the Pharisees were offended when they heard this saying?”

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?

18But the things which proceed out of the mouth come out of the heart, and they defile the man.

19For out of the heart come evil thoughts, murders, adulteries, sexual sins, thefts, false testimony, and blasphemies.
