Moses Departs from Midian
18Moses went and returned to Jethro his father-in-law, and said to him, “Please let me go and return to my brothers who are in Egypt, and see whether they are still alive.” Jethro said to Moses, “Go in peace.”19Yahweh said to Moses in Midian, “Go, return into Egypt; for all the men who sought your life are dead.”20Moses took his wife and his sons, and set them on a donkey, and he returned to the land of Egypt. Moses took God’s rod in his hand.
Exodus 4:18–20 depicts Moses requesting permission from his father-in-law Jethro to return to Egypt and his enslaved Hebrew brothers, which God confirms by assuring him that his former enemies are dead. Moses then departs with his family and God's rod, reversing his earlier flight and carrying the visible sign of his divine commission to liberate the captives.
Moses doesn't flee toward his mission—he walks toward it with his family, his faith reinforced, carrying in his hand the rod God has already proved belongs to Him.
Commentary
Exodus 4:18 — The Filial Request
Moses does not slip away; he returns to Jethro and asks permission. The phrase "my brothers who are in Egypt" is striking: after forty years in Midian, Moses still identifies himself with the enslaved Hebrews. His request is deliberately vague — he says nothing of divine visions, burning bushes, or a mission of liberation. Scholars have noted this reticence as either prudential humility or a sensitivity to what Jethro, a Midianite priest, could yet receive. The words "see whether they are still alive" echo the language of familial anxiety, perhaps also alluding to the ongoing genocide under Pharaoh. What matters pastorally is that Moses departs with blessing, not in breach: God's missions, even urgent ones, respect the bonds of human relationship and the order of family.
Exodus 4:19 — The Divine Reassurance
The repetition of God's command — "Go, return into Egypt" — is no redundancy. It is a pastoral act of encouragement. Moses has just expressed his fear of death at the burning bush (Exod 3:6, 4:1); here, God directly removes one layer of that fear: "all the men who sought your life are dead." This echoes a similar reassurance later given to the prophet Elijah (1 Kgs 19:1–18), who also fled into the wilderness in fear of death and was sent back to his mission. The phrase "in Midian" situates this as a private divine communication — God speaking to the heart of his servant mid-journey, not at a shrine or in a vision. The Catholic tradition recognizes in this the pattern of ongoing divine accompaniment: God does not call once and disappear; He sustains the called throughout their mission.
Exodus 4:20 — The Household in Motion
Moses gathers his wife Zipporah and his sons (Gershom, and likely Eliezer already born, cf. Exod 18:4) and sets them on a donkey — the humble beast of burden that will reappear at defining moments of salvation history. He "returned to the land of Egypt," a reversal of his original flight (Exod 2:15), now not in fear but in obedient purpose. The closing note is theologically charged: "Moses took God's rod in his hand." This is not a casual detail. The rod — which had just turned into a serpent before Yahweh and back again (Exod 4:2–4) — is now formally designated as "God's rod." The instrument of a shepherd has become the instrument of divine power. Moses carries in his hand the visible sign of his commission, the extension of God's own sovereignty into history.
Typological Senses
The Church Fathers consistently read Moses as a type of Christ. The descent into Egypt here foreshadows the Holy Family's flight into and return from Egypt (Matt 2:13–15), and Matthew explicitly cites Hosea 11:1 — "Out of Egypt I called my son" — applying it to Jesus. But the typology works in both directions here: just as Moses returns to Egypt to set the captives free, Christ descends into the realm of human bondage and death to accomplish the definitive Exodus. The rod in Moses's hand prefigures the Cross: an instrument of wood by which divine power is mediated, through which captivity is broken and the enemy overcome. Origen (Homilies on Exodus, Hom. 3) reads Moses's rod as a figure of the wood of the Cross, by which the serpent-enemy is stripped of his power.
Catholic Commentary
Catholic tradition illuminates this passage through several interconnected lenses.
Vocation and Obedience. The Catechism of the Catholic Church teaches that God's call demands a free and total response (CCC 2084). Moses models this perfectly: he does not abandon his obligations but reorders them — honoring Jethro, gathering his family — before he goes. This is not hesitation but integrated obedience, the kind described by St. Thomas Aquinas as the virtue of prudence ordering the goods of charity.
The Divine Pedagogy. God's reassurance in verse 19 exemplifies what CCC 53 calls the "divine pedagogy" — God progressively revealing Himself and accompanying His people in their weakness. He does not rebuke Moses for needing encouragement; He provides it. The Second Vatican Council's Dei Verbum (§2) speaks of God communicating Himself to humanity through deeds and words, and this intimate word in Midian is precisely such a moment.
The Rod as Sacramental Sign. St. Augustine (Quaestiones in Heptateuchum, II.2) and later medieval commentators understood "the rod of God" as a prototype of sacramental instrumentality: created matter taken up by divine power to become efficacious for salvation. This anticipates the Catholic theology of sacraments as instruments of grace — ordinary things (water, oil, bread, wood) made extraordinary by God's indwelling purpose.
The Family as Pilgrim Church. That Moses brings his entire household into the mission foreshadows the Church's consistent teaching that the domestic church (Ecclesia domestica, cf. Lumen Gentium §11) participates in the mission of the People of God. No one is left behind in God's call; the family travels together toward the promised liberation.
For Today
Contemporary Catholics frequently experience the gap between sensing a divine call and actually acting on it — whether to a vocation, a ministry, a work of mercy, or a courageous stand in the workplace or family. Moses in these verses offers three concrete lessons. First, honor the relationships you are leaving or adjusting: tell Jethro. God's urgency does not negate human duty; it deepens it. Second, when God reassures you that the obstacles have been removed, believe Him and move — do not manufacture new fears. Many stall at the edge of their Egypt because they keep inventorying old dangers God has already dealt with. Third, pick up the rod. Each of us has been given particular gifts, experiences, and even wounds that God has already claimed as His instruments. The Catholic who prays and serves with the "rod" of their specific charism — not someone else's — is the one through whom God acts. The donkey, the family, the ordinary road to Egypt: God's great works begin in humble, concrete steps of obedience.
