Mark 7:28 Context"For a certain woman, whose young daughter had an unclean spirit, heard of him, and came and fell at his feet: The woman was a Greek, a Syrophenician by nation; and she besought him that he would cast forth the devil out of her daughter. But Jesus said unto her, Let the children first be filled: for it is not meet to take the children's bread, and to cast it unto the dogs. Mark 7:28 And she answered and said unto him, Yes, Lord: yet the dogs under the table eat of the children's crumbs. And he said unto her, For this saying go thy way; the devil is gone out of thy daughter."
This is remarkable. The woman was given a hard answer, but she didn't give up. That's how humble we (i) need to be to get spiritual understanding.
