Mark 7:14-30
Again Jesus called the crowd to him and said, "Listen to me, everyone, and understand this. Nothing outside you can defile you by going into you. Rather, it is what comes out of you that defiles you."
After he had left the crowd and entered the house, his disciples asked him about this parable. "Are you so dull?" he asked. "Don't you see that nothing that enters you from the outside can defile you? For it doesn't go into your heart but into your stomach, and then out of your body." (In saying this, Jesus declared all foods clean.)
He went on: "What comes out of you is what defiles you. For from within, out of your hearts, come evil thoughts, sexual immorality, theft, murder, adultery, greed, malice, deceit, lewdness, envy, slander, arrogance and folly. All these evils come from inside and defile you."
Jesus left that place and went to the vicinity of Tyre. He entered a house and did not want anyone to know it; yet he could not keep his presence secret. In fact, as soon as she heard about him, a woman whose little daughter was possessed by an unclean spirit came and fell at his feet. The woman was a Greek, born in Syrian Phoenicia. She begged Jesus to drive the demon out of her daughter.
"First let the children eat all they want," he told her, "for it is not right to take the children's bread and toss it to the dogs."
"Lord," she replied, "even the dogs under the table eat the children's crumbs."
Then he told her, "For such a reply, you may go; the demon has left your daughter."
She went home and found her child lying on the bed, and the demon gone.
