Matthew 15:11-18

11It is not what goes into the mouth of a man that defiles and dishonors him, but what comes out of the mouth, this defiles and dishonors him.”

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

13He answered, “Every plant which My heavenly Father did not plant will be torn up by the roots.

14Leave them alone; they are blind guides [leading blind followers]. If a blind man leads a blind man, both will fall into a pit.”

15Peter asked Him, “Explain this parable [about what defiles a person] to us.”

16And He said, “Are you still so dull [and unable to put things together]?

17Do you not understand that whatever goes into the mouth passes into the stomach, and is eliminated?

18But whatever [word] comes out of the mouth comes from the heart, and this is what defiles and dishonors the man.
