Foreign Slaves: A Permitted but Bounded Institution
44“‘As for your male and your female slaves, whom you may have from the nations that are around you, from them you may buy male and female slaves.45Moreover, of the children of the aliens who live among you, of them you may buy, and of their families who are with you, which they have conceived in your land; and they will be your property.46You may make them an inheritance for your children after you, to hold for a possession. Of them you may take your slaves forever, but over your brothers the children of Israel you shall not rule, one over another, with harshness.
Leviticus 25:44–46 distinguishes between Hebrew and foreign slaves, permitting Israelites to own non-Israelites and their children born in the land as perpetual hereditary property. The passage concludes with a critical prohibition: Israelites may not rule their kinfolk "with harshness," deliberately invoking the Pharaonic oppression from which Israel had just been freed.
Israel permits slavery for foreigners but forbids harsh rule over its own—revealing how even God's chosen people can draw a circle of moral concern that excludes the outsider, a boundary Christ came to erase.
Commentary
Leviticus 25:44 — Acquisition of foreign slaves Verse 44 opens with the phrase "as for your male and female slaves" (Hebrew: 'eved and 'amah), immediately distinguishing the category under discussion from the Hebrew debt-servant addressed in vv. 39–43. The nations "around you" (sĕvîvôtêkem) refers to the Canaanite and other peoples among whom Israel lived; their inhabitants could be purchased outright as property. The verb "buy" (qānāh) carries commercial weight: this is a transaction of ownership, not merely contracted service. This verse therefore establishes chattel slavery — perpetual ownership of a person — as legally tolerated for non-Israelites, a stark contrast to the protections just extended to Israelite kin.
Leviticus 25:45 — Children of resident aliens Verse 45 extends the category to tôshāvîm, "aliens who sojourn among you" — not foreign enemies but people already integrated into Israelite society. Their children, even those born on Israelite soil, could be purchased and would become property ('ăhuzzāh, the same word used for land inheritance in the Jubilee legislation). This is legally and morally the most arresting detail: it denies birthright to children born in the land, assigning them a hereditary servile status. The contrast with the Jubilee's liberation theology (vv. 10–17) is intentional and pointed — the freedom proclaimed by the Jubilee is, in this legal code, ethnically bounded.
Leviticus 25:46 — Perpetual hereditary possession, and the crucial limiting clause Verse 46 confirms that foreign slaves can be willed to one's children as an 'ăhuzzāh ("holding," "possession") — the same terminology used for land tenure — making their servitude transgenerational. Yet the verse ends with the moral axis around which the entire chapter turns: "over your brothers the children of Israel you shall not rule, one over another, with harshness (bepereck)." The word pereck (harshness, ruthlessness) echoes Exodus 1:13–14, where it describes Pharaoh's oppression of Israel. Its appearance here is no accident: Israel, having been the enslaved, is forbidden to become Pharaoh toward its own kin. The implicit but unresolved theological question is why this logic of anti-Pharaonic mercy should stop at ethnic lines.
The typological and spiritual senses The Church reads the Old Testament through a fourfold lens. Literally, this is civil legislation for a Bronze Age theocracy. Allegorically, the distinction between "brother Israelites" and "foreigners" foreshadows the breaking-down of that wall in Christ (Eph 2:14), who makes all peoples into one household. The harsh treatment forbidden toward Israelite brothers is precisely what Gentiles also deserve — and receive — in the New Covenant. Morally, the passage warns every reader that it is dangerously easy to construct a circle of moral concern that includes "our people" and excludes the outsider; the New Testament systematically demolishes that circle. Anagogically, the Jubilee vision of universal freedom — glimpsed in vv. 10–17 but here still partial — points toward the eschatological liberty of the children of God (Rom 8:21).
Catholic Commentary
Catholic moral theology has long wrestled with the fact that the Mosaic Law tolerated, and in places regulated, institutions — including chattel slavery — that the Church now firmly condemns as intrinsically evil. This passage is a paradigm case of what theologians call the accommodatio or condescensio of divine pedagogy: God meeting a people where they were, gradually educating them toward a fuller moral vision. St. Thomas Aquinas distinguished between the natural law, which is universal and immutable, and the judicial precepts of the Old Law, which were particular positive enactments suited to the historical condition of Israel and which ceased to bind with the coming of Christ (Summa Theologiae I-II, q. 104, a. 3). These verses belong to the latter category; they carry no permanent moral authority.
The Second Vatican Council's Gaudium et Spes §27 explicitly names slavery among the "infamies" that "poison human society" and "are a supreme dishonour to the Creator." Gaudium et Spes §29 grounds the equality of all persons in their creation in the image of God (imago Dei) — a dignity that transcends race, nationality, and legal status. Pope John Paul II's Veritatis Splendor §80 identifies certain acts — including the reduction of persons to property — as intrinsece malum, intrinsically evil acts that no circumstance, intention, or social custom can justify. The Catechism of the Catholic Church §2414 explicitly states: "The seventh commandment forbids acts or enterprises that for any reason — selfish or ideological, commercial, or totalitarian — lead to the enslavement of human beings."
St. Gregory of Nyssa, centuries before the Magisterium's definitive teaching, was perhaps the earliest voice in the Christian tradition to argue from creation theology to the absolute incompatibility of slavery with human dignity (Homilies on Ecclesiastes, Homily 4). His argument — that to own a human being is to presume to override the lordship of God, who alone owns every soul — anticipates the Church's mature teaching by over a millennium and models how the spiritual reading of Scripture can outpace its civil-legal surface.
For Today
For contemporary Catholics, this passage is a school in moral humility and hermeneutical honesty. It warns against two equal and opposite errors: the fundamentalist error of treating every Mosaic civil regulation as a timeless divine mandate, and the dismissive error of discarding the Old Testament as morally irrelevant.
The more demanding practical application is this: these verses show how communities of faith can institutionalize injustice toward "outsiders" while maintaining genuine piety toward "insiders." Israel was not cynically hypocritical — the Jubilee law protecting Hebrew kin was sincere and beautiful. Yet the circle of moral concern stopped at the ethnic boundary. Catholics today must ask where our own circle of concern quietly stops: at national borders? at economic class? at the legally documented? at the unborn but not the incarcerated? The prophetic corrective is not simply to feel guilty but to allow the trajectory of Scripture — from Mosaic accommodation, through the prophets' universalism, to Christ's dismantling of the dividing wall — to actively expand our moral imagination. The Church's social teaching on human dignity (see Laudato Si' §65) demands nothing less.
