We must therefore introduce into this work an explanation of the generations of the three sons of Noah, in so far as that may illustrate the progress in time of the two cities. Scripture first mentions that of the youngest son, who is called Japheth: he had eight sons, and by two of these sons seven grandchildren, three by one son, four by the other; in all, fifteen descendants. Ham, Noah's middle son, had four sons, and by one of them five grandsons, and by one of these two great-grandsons; in all, eleven. After enumerating these, Scripture returns to the first of the sons, and says, "Cush begat Nimrod; he began to be a giant on the earth. He was a giant hunter against the Lord God: wherefore they say, As Nimrod the giant hunter against the Lord. And the beginning of his kingdom was Babylon, Erech, Accad, and Calneh, in the land of Shinar. Out of that land went forth Assur, and built Nineveh, and the city Rehoboth, and Calah, and Resen between Nineveh and Calah: this was a great city." Now this Cush, father of the giant Nimrod, is the first-named among the sons of Ham, to whom five sons and two grandsons are ascribed. But he either begat this giant after his grandsons were born, or, which is more credible, Scripture speaks of him separately on account of his eminence; for mention is also made of his kingdom, which began with that magnificent city Babylon, and the other places, whether cities or districts, mentioned along with it. But what is recorded of the land of Shinar which belonged to Nimrod's kingdom, to wit, that Assur went forth from it and built Nineveh and the other cities mentioned with it, happened long after; but he takes occasion to speak of it here on account of the grandeur of the Assyrian kingdom, which was wonderfully extended by Ninus son of Belus, and founder of the great city Nineveh, which was named after him, Nineveh, from Ninus. But Assur, father of the Assyrian, was not one of the sons of Ham, Noah's middle son, but is found among the sons of Shem, his eldest son. Whence it appears that among Shem's offspring there arose men who afterwards took possession of that giant's kingdom, and advancing from it, founded other cities, the first of which was called Nineveh, from Ninus. From him Scripture returns to Ham's other son, Mizraim; and his sons are enumerated, not as seven individuals, but as seven nations. And from the sixth, as if from the sixth son, the race called the Philistines are said to have sprung; so that there are in all eight. Then it returns again to Canaan, in whose person Ham was cursed; and his eleven sons are named. Then the territories they occupied, and some of the cities, are named. And thus, if we count sons and grandsons, there are thirty-one of Ham's descendants registered.
