1 Chronicles 1:24 (KJV)

And unto Eber were born two sons: the name of the one was Peleg; because in his days the earth was divided: and his brother's name was Joktan.

And Joktan begat Almodad, and Sheleph, and Hazarmaveth, and Jerah,

Hadoram also, and Uzal, and Diklah,

And Ebal, and Abimael, and Sheba,

And Ophir, and Havilah, and Jobab. All these were the sons of Joktan.

Eber, Peleg, Reu,

Serug, Nahor, Terah,

Abram; the same is Abraham.

The sons of Abraham; Isaac, and Ishmael.

These are their generations: The firstborn of Ishmael, Nebaioth; then Kedar, and Adbeel, and Mibsam,
