10:21 And sons were also born to Shem (the older brother of Japheth), the father of all the sons of Eber.

10:22 The sons of Shem were Elam, Asshur, Arphaxad, Lud, and Aram. 10:23 The sons of Aram were Uz, Hul, Gether, and Mash. 10:24 Arphaxad was the father of Shelah, and Shelah was the father of Eber. 10:25 Two sons were born to Eber: One was named Peleg because in his days the earth was divided, and his brother’s name was Joktan.
