Why did Moses send his wife Zipporah back to her father in Exodus 18:2? Canonical Text “After Moses had sent back his wife Zipporah, his father-in-law Jethro had received her and her two sons.” (Exodus 18:2-3a) Historical Setting • Exodus dated c. 1446 BC (cf. 1 Kings 6:1; Ussher 1491 BC; variance only of a few decades). • Moses, age 80, had returned from Midian to confront Pharaoh (Exodus 7:7). • Zipporah, a Midianite (Exodus 2:16-21), initially accompanied Moses toward Egypt (Exodus 4:20). Sequence of Events Prior to the Separation 1. Commission at Horeb (Exodus 3). 2. Journey toward Egypt with Zipporah and their sons (Exodus 4:20). 3. Lodging-place incident where Yahweh “sought to kill” Moses until Zipporah circumcised their son (Exodus 4:24-26). 4. Narrative silence concerning Zipporah through the plagues and Exodus; she re-enters in Exodus 18. The literary gap is bridged by 18:2’s parenthetical note: Moses “had sent back” (Heb. šillach) his wife; Jethro “received” (Heb. laqaḥ) her. Probable Reasons Moses Sent Zipporah Home 1. Safety During the Plagues • Ten plagues devastated Egypt (Exodus 7–12). By removing Zipporah and the children, Moses shielded them from escalating danger—especially the death of the firstborn (Exodus 12:29). • Behavioral-science corollary: crisis leaders often relocate family to reduce cognitive load and maintain mission focus. 2. Covenant Compliance Tension • The circumcision crisis (Exodus 4:24-26) revealed Zipporah’s revulsion (“You are a bridegroom of blood to me,” v. 26). • Sending her to Midian avoided further domestic conflict while Moses shepherded Israel through covenantal obedience (cf. Genesis 17:10-14). Keil-Delitzsch, in situ, note that Zipporah “saw in circumcision a bloody mutilation,” prompting withdrawal. 3. Strategic Witness to Jethro • Jethro, priest of Midian, ultimately blesses Yahweh after hearing Zipporah’s firsthand reports (Exodus 18:9-12). • The reunited family becomes the occasion for Jethro’s confession and for his sage judicial counsel (Exodus 18:13-27), which Scripture presents as providential. 4. Logistical Realities of the Exodus • Three million people (Exodus 12:37, cf. Numbers 1:46) required constant leadership. • An extended absence from Midian was foreseeable; returning Zipporah ensured provision for her rather than exposing her to wilderness hardships before Sinai. 5. Cultural Custom • Ancient Near-Eastern campaigns often began with temporary family separation; precedent exists with Jacob’s divided camps (Genesis 32:7-8). • In Midianite society, the woman’s paternal household remained a recognized place of refuge and security (cf. Nuzi tablets). Archaeological and Geographic Context • Midianite pottery (e.g., Qurayyah Painted Ware) dated to the Late Bronze I supports a Midianite presence east of the Gulf of Aqaba matching biblical Midian. • Timna Valley smelter inscriptions reference “YHW” (Yahweh) alongside Midianite iconography, evidencing contact between Yahwistic worship and Midian. Theological Implications • Leadership Sacrifice: Moses models willingness to relinquish personal comforts for the redemptive mission, prefiguring Christ’s kenosis (Philippians 2:5-8). • Covenant Priority: Obedience to God’s covenant rites (circumcision) supersedes familial preferences, echoing Jesus’ words in Luke 14:26. • Providential Orchestration: God uses human decisions (Moses’ dismissal) to orchestrate greater revelation (Jethro’s conversion and judicial reforms). Typological Reflection • As Zipporah is sheltered while judgment falls on Egypt, believers are hid in Christ when divine wrath is poured out (Romans 5:9). • The reunion at Sinai anticipates the final gathering of God’s people in the heavenly Zion (Hebrews 12:22-24). Practical Applications • Spiritual leaders today may need to make temporary, strategic family arrangements to fulfill kingdom tasks, yet ultimately reunite and minister in unity. • Covenant signs (baptism, Lord’s Supper) must never be minimized to appease cultural discomfort. • Testimony of God’s works through family members often opens doors for gospel proclamation, as with Jethro. Conclusion Moses sent Zipporah back to her father for a constellation of reasons—protection during the plagues, relief of domestic tension after the circumcision episode, logistical practicality, and divine strategy for Jethro’s encounter with Yahweh. The decision aligns perfectly with the biblical chronology, covenant theology, and the overarching narrative of God’s redemptive plan. |
