Summary of the Whole Conquest and the Hardening of Hearts
16So Joshua captured all that land, the hill country, all the South, all the land of Goshen, the lowland, the Arabah, the hill country of Israel, and the lowland of the same,17from Mount Halak, that goes up to Seir, even to Baal Gad in the valley of Lebanon under Mount Hermon. He took all their kings, struck them, and put them to death.18Joshua made war a long time with all those kings.19There was not a city that made peace with the children of Israel, except the Hivites, the inhabitants of Gibeon. They took all in battle.20For it was of Yahweh to harden their hearts, to come against Israel in battle, that he might utterly destroy them, that they might have no favor, but that he might destroy them, as Yahweh commanded Moses.
Joshua 11:16–20 describes Joshua's comprehensive conquest of Canaan from the southern mountains to the northern Hermon region, killing all opposing kings in a prolonged military campaign. The passage emphasizes that God hardened the hearts of the Canaanite rulers to prevent any peaceful settlement except Gibeon, fulfilling the covenant promise and executing divine judgment on a people whose iniquity had reached completion.
God does not harden hearts by injecting wickedness but by withdrawing grace from those who have already refused it—making judgment the culmination of centuries of rejection, not its cause.
Commentary
Joshua 11:16 — The Scope of the Conquest The catalogue of territories is deliberately exhaustive: the hill country (central highlands), "all the South" (the Negev), the land of Goshen (a district in southern Canaan, distinct from Egyptian Goshen), the Shephelah or lowland foothills, the Arabah (the great rift valley), and the northern hill country of Israel. The repetition of "all" (Hebrew kol) is a literary signature of this closing summary: the narrator insists that not a portion of the promised land escaped Joshua's reach. This completeness is covenantal — Yahweh said He would give "all the land," and the narrative fulfills that word.
Joshua 11:17 — The Geographical Boundaries Mount Halak ("the bare mountain") in the south anchors one pole of the conquest, likely near the modern Negev highlands toward Edom. Baal Gad beneath Mount Hermon anchors the northern pole in the Beqa Valley of modern Lebanon. Together they define the full extent of the land as promised, from the edge of the wilderness to the foot of the great northern mountain — a mountain Deuteronomy 3:25 associates with Moses' longing. That Joshua attains what Moses could only desire from afar is significant: conquest is the fruit of faithful leadership succeeding faithful leadership. The killing of all the kings is brutal in its starkness; it is the fulfillment of the ḥerem (sacred ban), the theological core of Deuteronomic warfare theology.
Joshua 11:18 — "A Long Time" This brief note is historically and spiritually important. The conquest was not a sudden, miraculous sweep but a prolonged military effort. Rabbinic tradition (Seder Olam) calculates seven years of war. The acknowledgment that "Joshua made war a long time" guards against a magical reading of divine assistance: God's Providence works through sustained human effort, patience, and sacrifice, not only through spectacular interventions like Jericho's walls.
Joshua 11:19 — The Gibeonite Exception The only city to make peace with Israel was Gibeon — and they did so by deceit (Joshua 9). The narrator's irony is pointed: the one city spared was spared through a ruse that exploited Israel's failure to consult God (9:14). Yet within the providential economy, this deception served God's larger purposes; the Gibeonites became a paradigm of the Gentile who, by cunning or desperation, finds shelter within the covenant community. Patristic writers would later read the Gibeonites as a type of the Church drawn from the nations.
Joshua 11:20 — The Hardening of Hearts This is the passage's most theologically demanding verse. The hardening of the Canaanites' hearts is ascribed directly to Yahweh — mē'ēt YHWH hāytāh ("it was from Yahweh"). The parallel with the hardening of Pharaoh's heart in Exodus (4:21; 7:3; 9:12) is unmistakable and deliberate. In both cases, divine hardening does not create wickedness where none existed but rather ratifies and accelerates a self-chosen trajectory of rebellion. The purpose stated — "that he might utterly destroy them, that they might have no favor" — must be read against the backdrop of Genesis 15:16, where God tells Abraham the iniquity of the Amorites is "not yet complete." The conquest represents the culmination of centuries of divine patience; the hardening is eschatological judgment upon a fully ripened sin.
Typological Sense In the allegorical reading favored by Origen (and taken up by Jerome), the Canaanite kings are the vices of the soul that must be conquered without negotiation. The hardening of their hearts signifies that entrenched sin ultimately loses its capacity to choose repentance — a spiritual law as well as a historical one. Joshua himself, whose name is identical to Jesus (Yēshûaʿ), prefigures Christ who conquers not earthly territories but the powers of death and darkness (Col 2:15).
Catholic Commentary
The hardening of hearts in verse 20 presents one of Scripture's most acute challenges to the Catholic understanding of God's justice, mercy, and human freedom — and Catholic tradition's engagement with it is rich and nuanced.
Providence and Human Freedom The Catechism of the Catholic Church teaches that "God is the sovereign master of his plan" (CCC 306) and that He "permits" evil while bringing good from it (CCC 311–312). The hardening of the Canaanites is not God imposing malice upon neutral wills but God permitting — and in a secondary sense directing — what those wills had already chosen. St. Thomas Aquinas, following Augustine (De Gratia et Libero Arbitrio), distinguishes between God as the "cause of the act" and man as the "cause of the defect": hardening is the withdrawal of grace from those who have persistently refused it (Summa Theologiae I–II, q. 79, a. 3).
The Analogy of Pharaoh St. John Chrysostom (Homilies on Romans 16) treats the Pharaoh parallel at length: "God does not harden by giving wickedness, but by not giving assistance." The Canaanites, like Pharaoh, had accumulated generations of moral debt (cf. Gen 15:16). Their hardening is God's judicial ratification of their freely chosen apostasy — what modern theology calls a "hardening from below" permitted rather than caused by God.
The Ḥerem and the Theology of Sacred War The Church Fathers (Origen, Homilies on Joshua 11) read the ḥerem — total destruction — as a type of baptismal renunciation: the Christian must not merely wound but destroy every vestige of sin, refusing to negotiate. Pope St. Gregory I echoed this in his moral exegesis: a half-conquered vice will reassert dominion.
The Gibeonite Exception as Type of the Church Patristic tradition (Justin Martyr, Dialogue with Trypho 111) identified the scarlet cord of Rahab and the survival of the Gibeonites as figures of salvation extended to the Gentiles — the Church gathered from all nations who find refuge in the name of the Lord.
For Today
Contemporary Catholics can feel discomfort at a God who "hardens hearts" — but this discomfort is itself a spiritual invitation. The passage calls us to honest examination: our hearts too can be hardened, not by divine fiat but by the gradual accumulation of small refusals — of grace, of conscience, of mercy offered to others. The Catechism warns explicitly against the "hardness of heart" that prevents repentance (CCC 1859).
The Gibeonites offer the counter-image: even the most unworthy, even those who approach God through imperfect motives or with a history of deception, can find shelter within the covenant. This should encourage Catholics who approach the sacrament of Reconciliation burdened by shame — God did not turn away those who came to Joshua with worn sandals and stale bread. He will not turn away those who come to the confessional with worn consciences and honest sorrow.
Verse 18's "long time" is also a grace note for the spiritual life. The interior conquest — putting to death the "kings" of habitual sin — is seldom sudden. It is the work of years of prayer, sacramental life, and patient spiritual direction. Perseverance, not spectacle, is the ordinary shape of Christian victory.
