This chapter shows more particularly what was said in general (Gen 9:19), concerning the three sons of Noah, that "of them was the whole earth overspread;" and the fruit of that blessing (Gen 9:1, Gen 9:7), "replenish the earth." Is is the only certain account extant of the origin of nations; and yet perhaps there is no nation but that of the Jews that can be confident from which of these seventy fountains (for so many there are here) it derives its streams. Through the want of early records, the mixtures of people, the revolutions of nations, and distance of time, the knowledge of the lineal descent of the present inhabitants of the earth is lost; nor were any genealogies preserved but those of the Jews, for the sake of the Messiah, only in this chapter we have a brief account, I. Of the posterity of Japheth (Gen 10:2-5). II. The posterity of Ham (Gen 10:6-20), and in this particular notice is taken of Nimrod (Gen 10:8-10). III. The posterity of Shem (Gen 10:21, etc.).
