Ishbak

Ishbak was a son of Abraham by his concubine Keturah, listed alongside his brothers Zimran, Jokshan, Medan, Midian, and Shuah in Genesis 25:2 and 1 Chronicles 1:32. The sons of Keturah are presented as the ancestors of various Arabian and Transjordanian peoples who were neighbors of Israel. No further deeds or descendants of Ishbak are specified in Scripture, and his name has not been definitively linked to any known ancient tribe or region.
