Matthew 15:21-28: Jesus left there and departed for the district of Tyre and Sidon.  It happened that a Canaanite woman living in that area came and cried out to Jesus, “Heir to the House of David, have pity on me!  My daughter is horribly demon-possessed.”

Jesus gave her no word of response.  The disciples came up and repeatedly said to him, “Please get rid of her!  She keeps calling after us.”  

Finally Jesus turned to the woman and said, “My mission is only to the lost sheep of the House of Israel.”  
She then prostrated herself before him with the plea, “Help me, Rabbi!” 

Jesus answered, “But it isn’t right to take the children’s food and throw it to the dogs.”  

“True, Rabbi,” she replied, “but even the dogs get to eat the scraps that fall from the table.”  
Jesus then said in reply, “Woman, you have great faith!  Your wish will come to pass.”  At that very moment her daughter was healed.
