Matthew 15:13-21

He answered, “Every plant which My heavenly Father did not plant will be torn up by the roots. [Is 60:21] Leave them alone; they are blind guides [leading blind followers]. If a blind man leads a blind man, both will fall into a pit.” Peter asked Him, “Explain this parable [about what defiles a person] to us.” And He said, “Are you still so dull [and unable to put things together]? Do you not understand that whatever goes into the mouth passes into the stomach, and is eliminated? But whatever [word]comes out of the mouth comes from the heart, and this is what defiles and dishonors the man. For out of the heart come evil thoughts and plans, murders, adulteries, sexual immoralities, thefts, false testimonies, slanders (verbal abuse, irreverent speech, blaspheming). These are the things which defile and dishonor the man; but eating with [ceremonially] unwashed hands does not defile the man.” After leaving there, Jesus withdrew to the district of Tyre and Sidon. [Mark 7:24-30]
