Genesis 25:1-6

1Now Abraham took another wife, 1whose name was Keturah. 22She bore to him Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. 3Jokshan fathered Sheba and Dedan. And the sons of Dedan were Asshurim, Letushim, and Leummim. 4The sons of Midian were Ephah, Epher, Hanoch, Abida, and Eldaah. All of these were the sons of Keturah. 53Now Abraham gave all that he had to Isaac; 6but to the sons of 4his concubines, Abraham gave gifts while he was still living, and 5sent them away from his son Isaac eastward, to the land of the east.
