Jethro

Jethro (meaning his excellence or his posterity; also called Reuel and Hobab) was the priest of Midian and father-in-law of Moses. After Moses fled Egypt and came to Midian, he served Jethro as a shepherd for forty years and married his daughter Zipporah, who bore him Gershom and Eliezer. When Moses returned to Midian after the Exodus, Jethro brought Zipporah and the boys to meet him in the wilderness and expressed worship of the LORD: "Now I know that the LORD is greater than all gods" (Exodus 18:8-12).

Jethro's most influential contribution was organizational. Observing Moses exhausting himself judging all disputes alone, Jethro advised him to delegate authority by appointing capable men as rulers of thousands, hundreds, fifties, and tens — a hierarchical judicial system that Moses implemented (Exodus 18:13-26). This advice from a Midianite priest-father-in-law shaped Israel's administrative structure at its formation and has been cited as an early example of management delegation. The episode reflects the surprising sources from which wisdom came in the ancient world, and the canonical inclusion of a Midianite's administrative counsel reflects the narrator's confidence that true wisdom is recognizable wherever it appears.
