Matthew 15:10-16

Jesus called the crowd to him and said, “Listen and understand. What goes into someone’s mouth does not defile them, but what comes out of their mouth, that is what defiles them.” Then the disciples came to him and asked, “Do you know that the Pharisees were offended when they heard this?” He replied, “Every plant that my heavenly Father has not planted will be pulled up by the roots. Leave them; they are blind guides. If the blind lead the blind, both will fall into a pit.” Peter said, “Explain the parable to us.” “Are you still so dull?” Jesus asked them.
