24 And from thence he arose, and went into the borders of Tyre and Sidon, and entered into an house, and would have no man know it: but he could not be hid.
25 For a certain woman, whose young daughter had an unclean spirit, heard of him, and came and fell at his feet:
26 The woman was a Greek,f a Syrophenician by nation; and she besought him that he would cast forth the devil out of her daughter.
27 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.
28 And she answered and said unto him, Yes, Lord: yet the dogs under the table eat of the children's crumbs.
29 And he said unto her,For this saying go thy way; the devil is gone out of thy daughter.
30 And when she was come to her house, she found the devil gone out, and her daughter laid upon the bed.
