2:23 The Caphtorim - A people a - kin to the Philistines, Gen 10:14, and confederate with them in this enterprize, and so dwelling together, and by degrees uniting together by marriages, they became one people. Caphtor - Which is by the learned thought to be Cappadocia: whither these people might make an expedition out of Egypt, either because of the report of the great riches of part of that country which drew others thither from places equally remote, or for some other reason now unknown.
2:8-23 We have the origin of the Moabites, Edomites, and Ammonites. Moses also gives an instance older than any of these; the Caphtorims drove the Avims out of their country. These revolutions show what uncertain things wordly possessions are. It was so of old, and ever will be so. Families decline, and from them estates are transferred to families that increase; so little continuance is there in these things. This is recorded to encourage the children of Israel. If the providence of God has done this for Moabites and Ammonites, much more would his promise do it for Israel, his peculiar people. Cautions are given not to meddle with Moabites and Ammonites. Even wicked men must not be wronged. God gives and preserves outward blessings to wicked men; these are not the best things, he has better in store for his own children.
