Ver. 21. Confines of Tyre. It perhaps may be asked, why Jesus went among the Gentiles, when he had commanded his apostles to avoid those countries? One reason may be, that our Saviour was not subject to the same rules he gave his disciples; another reason may be brought, that he did not go then to preach; hence St. Matthew observes that he kept himself retired. (St. Chrysostom) — Tyre and Sidon were both situated on the Mediterranean sea, about 20 miles distant from each other, and the adjoining country to the west and north of Galilee was called the coast or territories of Tyre and Sidon. The old inhabitants of this tract were descendants of Chanaan, (for Sidon was his eldest son) and continued in possession of it much longer than they did of any other part of the country. The Greeks called it Phœnicia; and when, by right of conquest, it became a province of Syria, it took the name of Syrophœnicia; hence the woman, whom St. Matthew calls a Chanaanite, St. Mark calls a Syrophœnician and Gentile; as being both by religion and language a Greek.
Ver. 22. It is probable that woman first cried out before the door, and assembled a crowd, and then went into the house. Have mercy on me. The great faith of the Chanaanæan woman is justly extolled. She believed him to be God, whom she calls her Lord, and him a man, whom she styles the Son of David. She lays no stress upon her own merits, but supplicates for the mercy of God; neither does she say, have mercy on my daughter, but have mercy on me. … To move him to compassion, she lays all her grief and sorrow before him in these afflicting words: my daughter is grievously afflicted by a devil. (Glossa.)
Ver. 23. He answered her not. It must not be supposed that our Saviour refused to hear the woman through any contempt, but only to shew that his mission was in the first instance to the Jews; or to induce her to ask with greater earnestness, so as to deserve more ample assistance. (Denis the Carthusian)
Ver. 26-27. And to cast it to the dogs; i.e. to Gentiles, sometimes so called by the Jews. (Witham) — The diminutive word Kunarios, or whelp, is used in both these verses in the Septuagint. Our Lord crosses the wishes of the Chanaanæan, not that he intended to reject her, but that he might bring to light the hidden and secret treasure of her virtue. Let us admire not only the greatness of her faith, but likewise the profoundness of her humility; for when our Saviour called the Jews children, so far from being envious of another's praise, she readily answers, and gives them the title of lords; and when Christ likened her to a dog, she presently acknowledges the meanness of her condition. (St. Chrysostom, hom. liii.) He refused at first to listen to her petition, says the same saint, to instruct us with what faith, humility, and perseverance we ought to pray. To make his servants more sensible of his mercy, and more eager to obtain it, he often appears to pay no attention to their prayers, till he had exercised them in the virtues of humility and patience. Ask, and you shall receive; knock, and it shall be opened to you. (Haydock)
Ver. 28. Be it done. In the beginning God said, Let there be light, and there was light; here Jesus Christ says, let it be done, &c. and her daughter was healed from that hour. So powerful with God is earnest and fervent prayer. (St. Chrysostom, hom. liii.)
