Catholic Commentary
The Sending of Moses and Aaron
26He sent Moses, his servant, and Aaron, whom he had chosen.27They performed miracles among them, and wonders in the land of Ham.
Psalms 105:26–27 recounts how God sent Moses and Aaron as His chosen servants to work miracles and signs in Egypt. The passage emphasizes that these wonders were expressions of God's power, not the achievements of the human agents, positioning both leaders as instruments through whom God demonstrated His authority over Pharaoh and Egypt.
God sends the unprepared and sustains them—not because they are ready, but because He wills their mission into being.
The pairing of the two figures also suggests the inseparability of word and sacrament in Catholic life: Moses speaks the prophetic word that interprets the signs; Aaron enacts the ritual that mediates God's saving presence. Neither operates alone.
Catholic tradition finds in these two verses a compact theology of divine mission and apostolic succession. The Catechism of the Catholic Church teaches that "God calls each one by name" (CCC 2158) and that all authentic ministry originates in divine commission, not human initiative — a principle Psalm 105:26 exemplifies with lapidary precision. Hebrews 5:4 makes this explicit in its theology of priesthood: "No one takes this honor upon himself, but he receives it when called by God, as Aaron was."
St. Gregory of Nyssa, in his Life of Moses, treats the entire Mosaic narrative as a spiritual itinerary, reading Moses' commissioning at the burning bush as a paradigm for every soul's encounter with the divine call — a sending that always exceeds the recipient's felt capacity (Moses protests his inadequacy; Ex 4:10) yet is sustained by God's own power. This patristic reading illuminates why Catholic spirituality insists that apostolic fruitfulness is rooted in obedience to God's call rather than personal talent.
Pope Benedict XVI, in Verbum Domini (2010), reflects on how the Old Testament pattern of prophetic sending reaches its fulfillment in the Incarnate Word: "In Christ, the fullness of divine revelation is given" (VD §3). The "signs" of Moses are thus read as anticipatory witnesses — real in themselves, but ordered toward a greater sign, the Paschal Mystery.
St. Thomas Aquinas (Summa Theologiae I–II, q. 98) situates the Mosaic Law within the economy of salvation as a pedagogy leading to Christ — precisely the framework Psalm 105 supports: God's acts through Moses are not ends in themselves but episodes in the single story of redemption.
For the contemporary Catholic, Psalm 105:26–27 issues a challenge to the pervasive temptation toward self-sufficiency in both ministry and personal vocation. The Psalmist is insistent: the decisive verb is He sent. This reorients the Christian who feels the weight of inadequacy in answering God's call — whether as a parent, a catechist, a priest, a deacon, or a lay leader in the workplace. The pattern of Moses resists the fantasy of the fully prepared minister: Moses was a fugitive shepherd when God sent him; Aaron was a bricklayer's overseer. Their fruitfulness came not from competence but from obedience to a commission that exceeded them.
Practically, a Catholic can pray these verses as a daily act of surrender: "Lord, it is you who send; equip what you commission." The verse also guards against clericalism and lay passivity alike — both Moses and Aaron were sent and chosen. Catholic social teaching, rooted in the baptismal call to holiness (Lumen Gentium §11), affirms that every lay person participates in God's ongoing mission in the world, working "signs" of justice, mercy, and truth in their particular sphere — not by their own power, but by the One who sends.
Commentary
Psalms 105:26 — "He sent Moses, his servant"
The verse opens with the emphatic subject: He — the LORD — sent. The Hebrew verb šālaḥ (to send, to commission) carries the full weight of prophetic and covenantal commissioning. This is not an appointment made by human initiative or popular acclaim; God Himself is the origin of Moses' authority. The title ʿebed ("servant") is a designation of profound honor in the Hebrew Bible. Far from connoting servility in the modern sense, ʿebed YHWH ("servant of the LORD") is the highest title of office in ancient Israel's theology — used for Abraham (Gen 26:24), Moses (Num 12:7; Josh 1:2), David (2 Sam 7:5), and the Suffering Servant of Isaiah. By calling Moses "his servant," the Psalmist does not diminish but exalts him, embedding him in the chain of chosen instruments through whom God acts in history.
Aaron is named alongside Moses, though grammatically he appears as a secondary figure — "Aaron, whom he had chosen" (the full verse in many manuscripts reads: "He sent Moses his servant, and Aaron whom he had chosen"). Aaron's explicit designation as chosen (bāḥar) echoes the Levitical and priestly election, grounding Aaron's authority not in birth alone but in divine election. The pairing of Moses (prophet/lawgiver) and Aaron (priest) is theologically freighted: the liberation of Israel required both prophetic word and priestly mediation — a duality the Church Fathers found deeply suggestive.
Psalms 105:27 — "They performed miracles among them"
The Hebrew for "miracles" here (dibrê ʾōtōtāyw, literally "words/matters of his signs") stresses that the wonders worked through Moses and Aaron are fundamentally God's signs — the human agents are vehicles, not originators. The phrase "among them" (bāhem) refers to the Egyptians, placing the signs in their native context of confrontation with Pharaoh. Psalm 105 is a rehearsal of the Heilsgeschichte (salvation history) in doxological form; it does not dwell on the plagues in isolation but presents them as coordinated acts of divine pedagogy and power, building toward Israel's liberation.
Typological and Spiritual Senses
The Church reads these verses on multiple levels. Allegorically, Moses is one of Scripture's most potent types (typos) of Christ: as Moses is sent by God to liberate Israel from Egyptian bondage, so Christ is sent by the Father (Jn 20:21) to liberate humanity from the bondage of sin and death. The "signs" worked by Moses in Egypt anticipate the "signs" () that structure the Gospel of John as demonstrations of divine glory. Aaron, the first high priest, prefigures Christ the eternal High Priest (Heb 7:11–17) — but crucially also the ministerial priesthood of the Church, which likewise acts not by its own authority but by divine commission.
