…and she bore him Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah.

Jokshan was the father of Sheba and Dedan. And the sons of Dedan were the Asshurites, the Letushites, and the Leummites.

But 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.

The sons born to Keturah, Abraham’s concubine: Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. The sons of Jokshan: Sheba and Dedan.
