Ishbak Article
STEPBible TIPNR
Ishbak is mentioned in two genealogical lists in the Bible (Gen.25.2, 1 Chronicles Gen 1:32) as one of the sons of Abraham by his concubine Keturah, whom he married after Sarah's death. Ishbak is listed along with his brothers Zimran, Jokshan, Medan, Midian, and Shuah. As a son of Abraham, Ishbak would have been sent away with gifts to the east country during Abraham's lifetime (Gen 25:6), preventing any rivalry with Isaac. The descendants of Ishbak are not mentioned further in the biblical narrative, and no additional details about his life are provided.
