1 Chronicles 1:32-37

Keturah, Abraham’s concubine, gave birth to Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. Then Jokshan had Sheba and Dedan. And Midian had Ephah, Epher, Hanoch, Abida, and Eldaah. These made up the Keturah branch. Abraham had Isaac, and Isaac had Esau and Israel (Jacob). Esau had Eliphaz, Reuel, Jeush, Jalam, and Korah. Eliphaz had Teman, Omar, Zepho, Gatam, Kenaz, Timna, and Amalek. And Reuel had Nahath, Zerah, Shammah, and Mizzah.
