Keturah was the wife of Abraham, whom he married after the death of Sarah. The account of Keturah and her descendants is found in the Book of Genesis. According to Genesis 25:1-4 , "Now Abraham had taken another wife, named Keturah, and she bore him Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. Jokshan was the father of Sheba and Dedan. The descendants of Dedan were the Asshurites, the Letushites, and the Leummites. The sons of Midian were Ephah, Epher, Hanoch, Abida, and Eldaah. All these were the descendants of Keturah."

Keturah's children are significant in the biblical narrative as they represent the extension of Abraham's lineage beyond Isaac and Ishmael. The descendants of Keturah are often associated with various tribes and regions in the ancient Near East.

Zimran: Little is known about Zimran, and the Bible does not provide further details about his descendants or their specific location. Some scholars suggest that Zimran's descendants may have settled in the Arabian Peninsula.

Jokshan: Jokshan fathered Sheba and Dedan. Sheba is often associated with the Sabeans, a people known for their wealth and trade, particularly in spices and gold. Dedan is linked to a trading community in northwestern Arabia, known for its caravan routes.

Medan and Midian: The Midianites, descendants of Midian, play a more prominent role in the biblical narrative. They are frequently mentioned in the context of trade and conflict with the Israelites. Moses' father-in-law, Jethro, was a priest of Midian (Exodus 3:1). The Midianites were involved in the sale of Joseph into slavery (Genesis 37:28) and later opposed Israel during their wilderness journey (Numbers 25:17-18).

Ishbak and Shuah: Like Zimran, the Bible provides limited information about Ishbak and Shuah. Some traditions and historical sources suggest that their descendants may have settled in regions of northern Arabia or Mesopotamia.

The descendants of Keturah, while not as central to the biblical narrative as the line of Isaac, represent the fulfillment of God's promise to Abraham that he would be the father of many nations (Genesis 17:4). These descendants contributed to the diverse ethnic and cultural landscape of the ancient Near East, interacting with the Israelites and other neighboring peoples throughout biblical history.
