“Shem, Arpachshad, Shelah; Eber, Peleg, Reu; Serug, Nahor, Terah; Abram, that is, Abraham.”
This section is based on Genesis, chapter 11, which has more details about these people. Here the names are listed without indicating how they are connected. This was also a partial duplication of the preceding verses. Now we only interested in Shem as the other two sons of Noah fade away. According to Genesis, (1) Shem’s 3rd son, (2) Arpachshad, had a son, (3) Shelah, who in turn had a son, Eber. (4) Eber also had a son, (5) Peleg. There is no mention of his brother Joktan and his 13 Arab sons here. Now Peleg seems more important, the reverse of the preceding section. This genealogy went into new territory as it follows the lineage of Peleg, not Joktan. Peleg had a son, (6) Reu, who shows up in the genealogies about Abraham. Reu also had a son, (7) Serug, who in turn had a son, named (8) Nahor. Nahor is the name of Abram’s grandfather and his brother. The older Nahor had a son, (9) Terah, who had 3 named sons, (10) Abram, Nahor, and Haran, so that Nahor was the name of the father of Terah and his son also. Now we get to the family background of Abram. Abram, who appears to be the oldest, took a wife named Sarai, who was barren. Sarai was his half sister, since Terah also had a concubine. Haran had three children, Lot, Milcah, and Iscah. However, he died early before his father Terah had died. They all lived at Ur in the Chaldeans, probably in northwest Mesopotamia. The younger brother of Abram, Nahor, took a wife named Milcah, who was the daughter of his brother Haran, who had died, the sister of Lot and Iscah. Thus Haran married his niece. Haran is a name that will appear again. More importantly, Terah became the father of Abram. So we have about 10 generations from Noah to Abram, about 400 years if you go by the first born. There is never any mention of daughters.
