New Defender's Study Bible Notes
25:3 Sheba, and Dedan. These two grandsons of Abraham by Keturah, seem to have been named after two grandsons of Cush (Genesis 10:7), although Shem also had a great grandson named Sheba (Genesis 10:22,24,25,28). One of these, probably the Cushite, evidently became the ancestor of the Sabaeans, and the Queen of Sheba (Job 1:15; I Kings 10:1). The Sabaeans have been well identified on the monuments as a kingdom in southwest Arabia, near modern Yemen.
