Genesis 25:1-6 New Revised Standard Version (NRSV)
Abraham Marries Keturah
25 Abraham took another wife, whose name was Keturah. 2 She bore him Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. 3 Jokshan was the father of Sheba and Dedan. The sons of Dedan were Asshurim, Letushim, and Leummim. 4 The sons of Midian were Ephah, Epher, Hanoch, Abida, and Eldaah. All these were the children of Keturah. 5 Abraham gave all he had to Isaac. 6 But to the sons of his concubines Abraham gave gifts, while he was still living, and he sent them away from his son Isaac, eastward to the east country.
