The son of Abraham and Keturah, Midian began a nomadic tribe which wandered the banks of the Red Sea as well as the Syrian desert. The Midianites had a close relationship with the Jewish people. For example, when Moses fled from Pharaoh, he went to the Midians and married Tzipporah, the daughter of a Medianite priest.
