John Lightfoot on Matthew 15:22

[A woman of Canaan.] In Mark it is, A Greek woman, a Syrophoenician by nation, chapter 7:26.

I. Of Canaan. It is worthy observing, that the Holy Bible, reckoning up the seven nations, which were to be destroyed by the Israelites, names the Perizzites, who were not at all recited among the sons of Canaan, Genesis 10; and the Canaanites as a particular nation, when all the seven, indeed, were Canaanites. See Deuteronomy 7:1, Joshua 9:1, 11:3, Judges 3:5, &c.

The reason of the latter (with which our business is) is to be fetched thence, that Canaan himself inhabited a peculiar part of that (northern) country, with his first-born sons, Sidon and Heth: and thence the name of Canaanites was put upon that particular progeny, distinguished from all his other sons; and that country was peculiarly called by the name of 'Canaan,' distinctly from all the rest of the land of Canaan. Hence Jabin, the king of Hazor, is called the 'king of Canaan,' Judges 4:2, and the kings of Tyre and Sidon, if I mistake not, are called 'the kings of the Hittites,' 1 Kings 10:29.

II. A Greek woman, a Syrophoenician Although Judea, and almost the whole world, had now a long while stooped under the yoke of the Romans, yet the memory of the Syro-Grecian kingdom, and the name of the nation, was not yet vanished. And that is worthy to be noted, In the captivity, they compute the years only from the kingdom of the Greeks. They said before, "That the Romans, for a hundred and fourscore years, ruled over the Jews before the destruction of the Temple"; and yet they do not compute the times to that destruction by the years of the Romans, but by the years of the Greeks. Let the Jews themselves well consider this, and the Christians with them, who reckon the Roman for the fourth monarchy in Daniel.

Therefore that woman that is here spoken of (to reduce all into a short conclusion) was a Syro-Grecian by nation, a Phoenician in respect of her habitation, and from thence called a woman of Canaan.
