18But those things which proceed out of the mouth come forth from the heart; and they defile the man.

19For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:

20These are the things which defile a man: but to eat with unwashen hands defileth not a man.

21Then Jesus went thence, and departed into the coasts of Tyre and Sidon.

22And, behold, a woman of Canaan came out of the same coasts, and cried unto him, saying, Have mercy on me, O Lord, thou son of David; my daughter is grievously vexed with a devil.

23But he answered her not a word. And his disciples came and besought him, saying, Send her away; for she crieth after us. [They looked down on the woman.]

24But he answered and said, I am not sent but unto the lost sheep of the house of Israel.

25Then came she and worshipped him, saying, Lord, help me.

26But he answered and said, It is not meet to take the children's bread, and to cast it to dogs. [This was for the diciples to hear]

27And she said, Truth, Lord: yet the dogs eat of the crumbs which fall from their masters' table.

28Then Jesus answered and said unto her, O woman, great is thy faith: be it unto thee even as thou wilt. And her daughter was made whole from that very hour.

29And Jesus departed from thence, and came nigh unto the sea of Galilee; and went up into a mountain, and sat down there.
He had traveled to Tyre to make the point of evil thoughts defileing a man, to help a woman of great faith, and then immediately walked all the way back.
