Genesis 25:1-6

¹Now Abraham took another wife, whose name was Keturah. ²She bore to him Zimran and Jokshan and Medan and Midian and Ishbak and Shuah. ³Jokshan became the father of Sheba and Dedan. And the sons of Dedan were Asshurim and Letushim and Leummim. ⁴The sons of Midian were Ephah and Epher and Hanoch and Abida and Eldaah. All these were the sons of Keturah. ⁵Now Abraham gave all that he had to Isaac; ⁶but to the sons of his concubines, Abraham gave gifts while he was still living, and sent them away from his son Isaac eastward, to the land of the east.
