1 Chronicles 1:21

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,

And Ebal, and Abimael, and Sheba,

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