A good man? Moses’ father-in-law, Jethro, is a devoted family man, well respected for his advice on governing and his benevolent leadership of the tribes of Midian. This early 13th-century illustration from the Bible moralisée depicts Jethro (seated under the arch on the right) rewarding Moses (left) for rescuing his daughters (six of whom are pictured in the center) and their flocks from rival shepherds. Grateful, Jethro invited Moses to stay and break bread with him: “Moses consented to stay with the man, and he gave Moses his daughter Zipporah as wife” (Exodus 2:21).

Later, when Moses returns from freeing the Israelites from Egypt, Jethro proclaims the Israelite God’s glory, saying, “Now I know that the Lord is greater than all gods” (Exodus 18:11). But, asks the midrash, was Jethro motivated by love of God or by fear of a divine force so powerful as to rescue the Israelites from their enemies?
