Matthew 15:22

And behold a woman of Canaan ,.... That is, of Phoenicia, which was called Canaan; so Shaul, the son of a Canaanitish woman, is, by the Septuagint in Exodus 6:15 called the son of a Phoenician; and the kings of Canaan are, by the same interpreters in Joshua 5:1 called kings of Phoenicia: hence this woman is by Mark said to be a Greek, that is, a Gentile, as the Jews used to call all of another nation, and a Syrophenician, being a native of Phoenicia, called Syrophenician; because it bordered upon Syria, and had been formerly a part of it, by conquest: so Cadmus, who is reported to have first brought letters from Phoenicia to Greece, is called F9 Lucian. Dialog. Deor. Coneil. sect. 2, a Syrophenician merchant.

Came out of the same coasts ; being an inhabitant, it is very likely, either of Tyre or Sidon: this shows that Christ did not go into these places, but only to the borders of them, since she is said to come out of them to him; who, having heard of him, and the miraculous cures wrought by him, and being informed that he was near, at such a place, as the Persic version says, "suddenly came forth out of a corner"; and the Ethiopic reads it, "out of the mountains thereof"; and made to the house where he was privately retired, and would have hid himself, as Mark suggests,

saying, have mercy on me ; meaning, by curing her daughter, with whose case she was so much affected, that she made it, as it were, her own:

O Lord, thou son of David . The first of these characters expresses her faith in his power, dominion, and government, that all persons and things, and so all diseases were at his command, and control; and that being Lord of all, he could remove them at his pleasure: the other shows her knowledge and belief of him, as the Messiah, that being a name by which he was usually known by the Jews; See Gill on Matthew 1:1 and which she, though a Gentile, might come at the knowledge of, either through being a proselyte to the Jewish religion, or through a general report which might reach, especially the neighbouring nations, that the Jews expected a wonderful deliverer to arise among them, under this character of the son of David; and from what she had heard of him, she concluded he must be the person.

My daughter is grievously vexed with a devil , which had took possession of her, and most grievously afflicted her: and her request to him was, that he would cast him out of her: believing he had power so to do, without seeing or touching her, only by a word speaking: her faith was like that of the centurion's.
