Jethro (jç'thro or jĕth'ro), his excellence. A priest or prince of Midian, and father-in-law of Moses. Exodus 3:1. He is called Raguel (R. V. "Reuel"), Numbers 10:29, and Reuel, Exodus 2:18, and was probably known by either name, while Jethro was his official title. It is highly probable, too, that he was a descendant of Abraham by Keturah, the mother of Midian, Genesis 25:2; but what was the nature of his office as priest—or prince, as some say it should be rendered—we know not.
