In context
1Now Abraham had taken another wife, named Keturah, 2and she bore him Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. 3Jokshan was the father of Sheba and Dedan. And the sons of Dedan were the Asshurites, the Letushites, and the Leummites. 4The sons of Midian were Ephah, Epher, Hanoch, Abida, and Eldaah. 5Abraham left everything he owned to Isaac. 6But while he was still alive, Abraham gave gifts to the sons of his concubines and sent them away from his son Isaac to the land of the east.
