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.

Now these are the generations - It is extremely difficult to say what particular nations and people sprang from the three grand divisions of the family of Noah, because the names of many of those ancient people have become changed in the vast lapse of time from the deluge to the Christian era; yet some are so very distinctly marked that they can be easily ascertained, while a few still retain their original names.

Moses does not always give the name of the first settler in a country, but rather that of the people from whom the country afterwards derived its name. Thus Mizraim is the dual of Mezer, and could never be the name of an individual. The like may be said of Kittim, Dodanim, Ludim, Ananim, Lehabim, Naphtuhim, Pathrusim, Casluhim, Philistim, and Caphtorim, which are all plurals, and evidently not the names of individuals, but of families or tribes. See Gen 10:4, Gen 10:6, Gen 10:13, Gen 10:14.

In the posterity of Canaan we find whole nations reckoned in the genealogy, instead of the individuals from whom they sprang; thus the Jebusite, Amorite, Girgasite, Hivite, Arkite, Sinite, Arvadite, Zemarite, and Hamathite, Gen 10:16-18, were evidently whole nations or tribes which inhabited the promised land, and were called Canaanites from Canaan, the son of Ham, who settled there. Moses also, in this genealogy, seems to have introduced even the name of some places that were remarkable in the sacred history, instead of the original settlers. Such as Hazarmaveth, Gen 10:26; and probably Ophir and Havilah, Gen 10:29. But this is not infrequent in the sacred writings, as may be seen Ch1 2:51, where Salma is called the father of Bethlehem, which certainly never was the name of a man, but of a place sufficiently celebrated in the sacred history; and in Ch1 4:14, where Joab is called the father of the valley of Charashim, which no person could ever suppose was intended to designate an individual, but the society of craftsmen or artificers who lived there.

Eusebius and others state (from what authority we know not) that Noah was commanded of God to make a will and bequeath the whole of the earth to his three sons and their descendants in the following manner: - To Shem, all the East; to Ham, all Africa; to Japheth, the Continent of Europe with its isles, and the northern parts of Asia. See the notes at the end of the preceding chapter, Gen 9:29 (note).

Now these are the generations of the sons of Noah,.... The genealogy of them, and which is of great use to show the original of the several nations of the world, from whence they sprung, and by whom they were founded; and to confute the pretended antiquity of some nations, as the Egyptians, Chaldeans, Chinese, and others; and to point out the particular people, which were to be the seat of the church of God for many ages, and from whom the Messiah was to spring; which seems to be the principal view of the history of Moses, and of this genealogy, with which should be compared Ch1 1:1 Shem, Ham, and Japheth; see Gen 5:32.

and unto them were sons born after the flood; for they had none born to them either before the flood or in it; they were married before the flood, for their wives went into the ark with them; but it does not appear they had any children before, though they then were near an hundred years old; and if they had, they were not in the ark, and therefore must perish with the rest, which is not likely: Shem's son Arphaxad was born two years after the flood, Gen 11:10 when the rest were born, either his or his brethren's, is not said; however they were all born after the flood; though some pretend that Canaan was born in the ark (y), during the flood, for which there is no authority; yea, it is confuted in this chapter, where Canaan stands among the sons of Ham, born to him after the flood.
