In the Old Testament or the Hebrew Bible, Jethro (; , Standard Yitro Tiberian ; "His Excellence/Posterity"; Arabic  Shu-ayb) or Reuel was Moses' father-in-law, a Kenite shepherd and priest of Midian. In Exodus, Moses' father-in-law is initially referred to as "Reuel" (Exodus 2:18) but then as "Jethro" (Exodus 3:1). He was the father of Hobab in the Book of Numbers 10:29. He is also revered as the spiritual founder and chief prophet in his own right in the Druze religion, and considered an ancestor of all Druze.
