Matthew 15:14-24

14 Leave them alone! They are blind leaders. When one blind person leads another, both will fall into the same pit."
15 Peter said to him, "Explain this illustration to us."
16 Jesus said, "Don't you understand yet?
17 Don't you know that whatever goes into the mouth goes into the stomach and then into a toilet?
18 But whatever goes out of the mouth comes from within, and that's what makes a person unclean.
19 Evil thoughts, murder, adultery, [other] sexual sins, stealing, lying, and cursing come from within.
20 These are the things that make a person unclean. But eating without washing one's hands doesn't make a person unclean."
21 Jesus left that place and went to the region of Tyre and Sidon.
22 A Canaanite woman from that territory came [to him] and began to shout, "Have mercy on me, Lord, Son of David! My daughter is tormented by a demon."
23 But he did not answer her at all. Then his disciples came to him and urged him, "Send her away. She keeps shouting behind us."
24 Jesus responded, "I was sent only to the lost sheep of the nation of Israel."
