Matthew 15:22-23 
A Canaanite woman from that vicinity came to him, crying out, "Lord, Son of David, have mercy on me! My daughter is suffering terribly from demon-possession." Jesus did not answer a word. 
So his disciples came to him and urged him, "Send her away, for she keeps crying out after us."

Matthew 15:25-27 
The woman came and knelt before him. "Lord, help me!" she said. 
He replied, "It is not right to take the children's bread and toss it to their dogs." 
"Yes, Lord," she said, "but even the dogs eat the crumbs that fall from their masters' table."
