Adam, Seth, Enosh, Kenan, Mahalalel, Jared, Enoch, Methuselah, Lamech. The sons of Noah: Shem, Ham, and Japheth. The sons of Japheth: Gomer, Magog, Madai, Javan, Tubal, Meshech, and Tiras. The sons of Gomer: Ashkenaz, Riphath, and Togarmah. And the sons of Javan: Elishah, Tarshish, the Kittites, and the Rodanites. The sons of Ham: Cush, Mizraim, Put, and Canaan. The sons of Cush: Seba, Havilah, Sabta, Raamah, and Sabteca. The sons of Raamah: Sheba and Dedan. Cush was the father of Nimrod, who began to be a mighty one on the earth. Mizraim was the father of the Ludites, the Anamites, the Lehabites, the Naphtuhites, the Pathrusites, the Casluhites (from whom the Philistines came), and the Caphtorites. And Canaan was the father of Sidon his firstborn, and of the Hittites, the Jebusites, the Amorites, the Girgashites, the Hivites, the Arkites, the Sinites, the Arvadites, the Zemarites, and the Hamathites. The sons of Shem: Elam, Asshur, Arphaxad, Lud, and Aram. The sons of Aram: Uz, Hul, Gether, and Meshech. Arphaxad was the father of Shelah, and Shelah was the father of Eber. Two sons were born to Eber: One was named Peleg, because in his days the earth was divided, and his brother was named Joktan. And Joktan was the father of Almodad, Sheleph, Hazarmaveth, Jerah, Hadoram, Uzal, Diklah, Obal, Abimael, Sheba, Ophir, Havilah, and Jobab. All these were sons of Joktan. So from Shem came Arphaxad, Shelah, Eber, Peleg, Reu, Serug, Nahor, Terah, and Abram (that is, Abraham).
This is the account of Shem. Two years after the flood, when Shem was 100 years old, he became the father of Arphaxad. And after he had become the father of Arphaxad, Shem lived 500 years and had other sons and daughters. When Arphaxad was 35 years old, he became the father of Shelah. And after he had become the father of Shelah, Arphaxad lived 403 years and had other sons and daughters. When Shelah was 30 years old, he became the father of Eber. And after he had become the father of Eber, Shelah lived 403 years and had other sons and daughters. When Eber was 34 years old, he became the father of Peleg. And after he had become the father of Peleg, Eber lived 430 years and had other sons and daughters. When Peleg was 30 years old, he became the father of Reu. And after he had become the father of Reu, Peleg lived 209 years and had other sons and daughters. When Reu was 32 years old, he became the father of Serug. And after he had become the father of Serug, Reu lived 207 years and had other sons and daughters. When Serug was 30 years old, he became the father of Nahor. And after he had become the father of Nahor, Serug lived 200 years and had other sons and daughters. When Nahor was 29 years old, he became the father of Terah. And after he had become the father of Terah, Nahor lived 119 years and had other sons and daughters. When Terah was 70 years old, he became the father of Abram, Nahor, and Haran. This is the account of Terah. Terah became the father of Abram, Nahor, and Haran. And Haran became the father of Lot. During his father Terah's lifetime, Haran died in his native land, in Ur of the Chaldeans. And Abram and Nahor took wives for themselves. Abram's wife was named Sarai, and Nahor's wife was named Milcah; she was the daughter of Haran, who was the father of both Milcah and Iscah.
Significance
These are parallel historiographical accounts of the Shemite genealogy from Shem to Abraham. Genesis 11:10-26 provides the תּוֹלְדוֹת (toledot, "generations") of Shem with detailed chronological data -- ages at fathering and total lifespans -- narrowing the line from Shem through Arphaxad, Shelah, Eber, Peleg, Reu, Serug, Nahor, and Terah to Abram. 1 Chronicles 1:24-27 compresses this same lineage into a bare name list, stripping away the chronological framework. The Chronicler's selective abbreviation serves a post-exilic audience that needs to trace David's (and Israel's) descent back to creation without the narrative detail, focusing on the line of election rather than the passage of time. Both texts share the same redemptive-historical function: demonstrating that God preserved a chosen line through the generations after the flood, culminating in the call of Abraham.
