"Moses' father-in-law," a shepherd-prince or priest of Midian, Exodus 3:1 4:18 18:1-27 . When the Hebrews were at mount Sinai, he visited Moses, gave him some wise counsel as to the government of the tribes, and then returned to his own people. See Exodus 18:10,11 , and some infer that he was a descendant of Abraham, through Midian, Genesis 25:2 .
