Genesis 25:1-4

Abraham married a second time; his new wife was named Keturah. She gave birth to Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. Jokshan had Sheba and Dedan. Dedan’s descendants were the Asshurim, the Letushim, and the Leummim. Midian had Ephah, Epher, Hanoch, Abida, and Eldaah—all from the line of Keturah.
