11 Now there was there nigh unto the mountains a great herd of swine feeding.
12 And all the devils besought him, saying, Send us into the swine, that we may enter into them.

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.

40 And I besought thy disciples to cast him out; and they could not.
41 And Jesus answering said, O faithless and perverse generation, how long shall I be with you, and suffer you? Bring thy son hither.
