Genesis 10
10:1 These are the descendants of Noah’s sons, Shem, Ham, and Japheth; children were born to them after the flood.
2The descendants of Japheth: Gomer, Magog, Madai, Javan, Tubal, Meshech, and Tiras. 3The descendants of Gomer: Ashkenaz, Riphath, and Togarmah. 4The descendants of Javan: Elishah, Tarshish, Kittim, and Rodanim.[i] 5From these the coastland peoples spread. These are the descendants of Japheth in their lands, with their own language, by their families, in their nations.[ii]
6The descendants of Ham: Cush, Egypt, Put, and Canaan. 7The descendants of Cush: Seba, Havilah, Sabtah, Raamah, and Sabteca. The descendants of Raamah: Sheba and Dedan.[iii] 8Cush became the father of Nimrod; he was the first on earth to become a mighty warrior. 9He was a mighty hunter before the Lord; therefore it is said, ‘Like Nimrod a mighty hunter before the Lord.’ 10The beginning of his kingdom was Babel, Erech, and Accad, all of them in the land of Shinar. 11From that land he went into Assyria, and built Nineveh, Rehoboth-ir, Calah, and 12Resen between Nineveh and Calah; that is the great city. 13Egypt became the father of Ludim, Anamim, Lehabim, Naphtuhim, 14Pathrusim, Casluhim, and Caphtorim, from which the Philistines come.
15Canaan became the father of Sidon his firstborn, and Heth, 16and the Jebusites, the Amorites, the Girgashites, 17the Hivites, the Arkites, the Sinites, 18the Arvadites, the Zemarites, and the Hamathites. Afterwards the families of the Canaanites spread abroad. 19And the territory of the Canaanites extended from Sidon, in the direction of Gerar, as far as Gaza, and in the direction of Sodom, Gomorrah, Admah, and Zeboiim, as far as Lasha. 20These are the descendants of Ham, by their families, their languages, their lands, and their nations.
21To Shem also, the father of all the children of Eber, the elder brother of Japheth, children were born.[iv] 22The descendants of Shem: Elam, Asshur, Arpachshad, Lud, and Aram. 23The descendants of Aram: Uz, Hul, Gether, and Mash.[v] 24Arpachshad became the father of Shelah; and Shelah became the father of Eber. 25To Eber were born two sons: the name of one was Peleg, for in his days the earth was divided, and his brother’s name was Joktan. 26Joktan became the father of Almodad, Sheleph, Hazarmaveth, Jerah, 27Hadoram, Uzal, Diklah, 28Obal, Abimael, Sheba, 29Ophir, Havilah, and Jobab; all these were the descendants of Joktan. 30The territory in which they lived extended from Mesha in the direction of Sephar, the hill country of the east. 31These are the descendants of Shem, by their families, their languages, their lands, and their nations.[vi]
32These are the families of Noah’s sons, according to their genealogies, in their nations; and from these the nations spread abroad on the earth after the flood.[vii]
[i] The Priestly genealogy of Chapter 10 lists the descendants of Noah's sons without employing the root ילד – to give birth. The Bridging source on the other hand uses this root in the qal, yalad (he gave birth), and the qal passive yulad (was born to). The P genealogy lists only the sons and the important grandsons of Noah's children, whereas B's list is much more prolific, since he wishes to arrive at the number 70, the number of the nations (and the gods) in Canaanite myth.
[ii] The summarizing verses for each of the sons (Shem Ham and Yephet) appear after two verses of naming their descendants, which is somewhat redundant. I posit that only the final verse (vs. 32): (These are the families of Noah’s sons, according to their genealogies, in their nations; and from these the nations spread abroad on the earth after the flood), which provides a fitting conclusion to the whole list, is original to the P genealogy. Such summarizing verses are appropriate to B's supplemented genealogy, which is much longer (except in the case of Yephet). Note also that only B really goes into a list of these nations lands (e.g. vs. 30), whereas P provides just a barebones list, the summarizing verses thus make more sense as B additions.
[iii] In B's genealogy of Chapter 25:1-6, Abraham was the grandfather of Sheva and Dedan, not Ham.
[iv] Note the addition of the short hero myth concerning Nimrod in vss. 8-11, this type of legend is similar to the sons of God text at the beginning of Chapter 6, and in my eyes is one of the defining features of late B texts. The hero myth is clearly connected to the secondary layer of this genealogy since it uses the root yalad (to give birth) as opposed to simply listing the sons, and see comment i.
B is careful to note that although Shem appears at the end of this genealogy he is the eldest son.
[v] The list of Shem's children provides the background for the Semite line as listed in Chapter 11.
[vi] The basis of some of this added genealogy is the Priestly list of the sons of Shem in the following chapter.
[vii] See comment ii. Note the number of Joktan’s children; it is likely that B, realizing he needed to get to seventy, gave Joktan more children than anyone else.
