Genesis 25:1-11

Abraham took another wife, whose name was Keturah. She bore him Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. Jokshan begot Sheba and Dedan. The descendants of Dedan were the Asshurim, the Letushim, and the Leummim. The descendants of Midian were Ephah, Epher, Enoch, Abida, and Eldaah. All these were descendants of Keturah. Abraham willed all that he owned to Isaac; but to Abraham's sons by concubines Abraham gave gifts while he was still living, and he sent them away from his son Isaac eastward, to the land of the East. This was the total span of Abraham's life: one hundred and seventy-five years. And Abraham breathed his last, dying at a good ripe age, old and contented; and he was gathered to his kin. His sons Isaac and Ishmael buried him in the cave of Machpelah, in the field of Ephron son of Zohar the Hittite, facing Mamre, the field that Abraham had bought from the Hittites; there Abraham was buried, and Sarah his wife. After the death of Abraham, God blessed his son Isaac. And Isaac settled near Beer-lahai-roi.
