Genesis 10:1

Moses begins with Japheth's family, either because he was the eldest, or because his family lay remotest from Israel and had least concern with them at the time when Moses wrote, and therefore he mentions that race very briefly, hastening to give an account of the posterity of Ham, who were Israel's enemies and of Shem, who were Israel's ancestors; for it is the church that the scripture is designed to be the history of, and of the nations of the world only as they were some way or other related to Israel and interested in the affairs of Israel. Observe, 1. Notice is taken that the sons of Noah had sons born to them after the flood, to repair and rebuild the world of mankind which the flood had ruined. He that had killed now makes alive. 2. The posterity of Japheth were allotted to the isles of the Gentiles (Gen 10:5), which were solemnly, by lot, after a survey, divided among them, and probably this island of ours among the rest; all places beyond the sea from Judea are called isles (Jer 25:22), and this directs us to understand that promise (Isa 42:4), the isles shall wait for his law, of the conversion of the Gentiles to the faith of Christ.
