The Generations of Ishmael
12Now this is the history of the generations of Ishmael, Abraham’s son, whom Hagar the Egyptian, Sarah’s servant, bore to Abraham.13These are the names of the sons of Ishmael, by their names, according to the order of their birth: the firstborn of Ishmael, Nebaioth, then Kedar, Adbeel, Mibsam,14Mishma, Dumah, Massa,15Hadad, Tema, Jetur, Naphish, and Kedemah.16These are the sons of Ishmael, and these are their names, by their villages, and by their encampments: twelve princes, according to their nations.17These are the years of the life of Ishmael: one hundred thirty-seven years. He gave up his spirit and died, and was gathered to his people.18They lived from Havilah to Shur that is before Egypt, as you go toward Assyria. He lived opposite all his relatives.
Genesis 25:12–18 records the genealogy and death of Ishmael, Abraham's son by Hagar, listing his twelve sons who became princes and nations, fulfilling God's earlier promise. Ishmael dies at 137 years old and is buried, having fathered a vast Arabian lineage from Havilah to Shur, demonstrating God's blessing upon his line despite his status outside the covenant succession.
God names Ishmael's twelve sons—none of whom will inherit the covenant—with the same sacred precision He uses for Israel, proving that faithfulness to the marginal is faithfulness to the covenant itself.
Commentary
Genesis 25:12 — The Toledot Formula and Ishmael's Identity The passage opens with the solemn formula elleh toledot — "these are the generations of" — which structures the entire book of Genesis as a series of ordered histories (cf. Gen 2:4; 5:1; 6:9; 10:1). That this formula is applied to Ishmael is significant: it signals that his line, too, is a genuine chapter in sacred history, not merely a genealogical footnote. Ishmael is carefully identified by both parents — "Abraham's son, whom Hagar the Egyptian, Sarah's servant, bore to Abraham" — a double identification that locates him precisely within the social and theological tensions of the narrative. He is Abraham's son by blood and promise, yet born of a servant and an Egyptian foreigner. This dual status has governed his story from birth and will echo in Paul's typological reading of the two mothers (Gal 4:21–31).
Verses 13–15 — The Twelve Sons by Name The twelve sons are listed in birth order, beginning with Nebaioth (whose sister Mahalath later married Esau, Gen 28:9) and Kedar (who becomes a byword for nomadic tent-dwelling in the Psalms and Isaiah). The names correspond to well-attested tribal and geographical entities in the ancient Near East: Tema appears in Job 6:19 and Isaiah 21:14 as a desert trading post; Dumah may correspond to the oasis of Dumat al-Jandal in northwest Arabia; Massa is associated in Proverbs 30–31 with a wisdom tradition ("the words of Agur son of Jakeh of Massa"). The list is thus historically anchored in the tribal landscape of the ancient Arabian and Syro-Arabian desert, spanning from Sinai to the Persian Gulf region. Far from being legendary, these are the ancestors of real peoples whose descendants appear throughout the historical and prophetic books.
Genesis 25:16 — Twelve Princes, Twelve Nations The concluding summary — "twelve princes, according to their nations" — directly echoes God's promise to Abraham in Genesis 17:20: "I will make him fruitful and will multiply him exceedingly; he will become the father of twelve princes, and I will make him a great nation." The fulfillment is exact and deliberate. The number twelve carries deep structural weight in Scripture: it anticipates the twelve tribes of Israel (Gen 35:22–26) and, ultimately, the twelve Apostles of the New Israel (Matt 10:1–4). The parallelism between Ishmael's twelve princes and Israel's twelve tribes invites reflection on the universality of God's providential ordering of history — different peoples, different roles, one sovereign God.
Genesis 25:17 — Ishmael's Death: "Gathered to His People" Ishmael dies at 137 years, an age that places him within the long-lived patriarchal tradition without reaching the antediluvian extremes. The phrase "he gave up his spirit and died, and was gathered to his people" is a reverential formula used for Abraham (Gen 25:8) and later for Isaac (Gen 35:29) and Jacob (Gen 49:33). Its application to Ishmael — not merely to the patriarchs of the covenant line — suggests a dignified recognition of his full humanity and his standing before God. The Fathers noted that Ishmael, though outside the Abrahamic covenant proper, was nonetheless circumcised (Gen 17:26) and thus bore upon his body the sign of the covenant.
Genesis 25:18 — Territory and the Echo of Prophecy The geographic range "from Havilah to Shur" mirrors the territory later associated with the Amalekites (1 Sam 15:7), and the phrase "before Egypt, as you go toward Assyria" traces a great arc of the ancient Near East, suggesting that Ishmael's descendants occupied a vast swathe of desert between the two great civilizations of antiquity. The closing clause — "he lived opposite all his relatives" (or "in hostility to all his brothers," echoing Gen 16:12) — closes the narrative arc of Ishmael's life with the very words spoken by the angel to Hagar at the well of Beer-lahai-roi. The prophecy has come full circle: a wild man, his hand against every man, yet also a man whom God heard (the very meaning of "Ishmael": Yishma'el, "God hears").
Catholic Commentary
Catholic tradition brings a distinctive hermeneutical depth to this genealogy by reading it within the broader economy of salvation without reducing Ishmael to a mere foil or negative type. St. Paul in Galatians 4:21–31 reads Hagar and Ishmael typologically as representing the covenant of the Law given at Sinai — the "slavery" of human effort — over against Sarah and Isaac representing the covenant of grace and freedom. This is an apostolic and canonical reading, received by the Church, but it is crucially a typological reading that concerns the two covenants, not a moral condemnation of Ishmael or his descendants as persons.
The Catechism of the Catholic Church (§s 145–147) reflects on Abraham as the father of faith precisely because God's promises extended through him to many peoples. The Church has consistently taught — following St. Augustine (City of God, Book XVI) and St. John Chrysostom (Homilies on Genesis, Homily 47) — that the Ishmaelites are genuine participants in God's providential plan for humanity, receiving temporal blessings and earthly greatness as fulfillment of divine promise.
Pope John Paul II, in Redemptoris Missio (§s 28–29), affirmed that the Holy Spirit works beyond the visible boundaries of the Church and that "seeds of the Word" (semina Verbi, a concept developed by Justin Martyr) are present in the religious traditions and histories of all peoples. The twelve princes of Ishmael, in this light, can be read as testifying to God's universal fatherhood, even while the specific saving covenant is ordered through Isaac, Jacob, and ultimately Christ. Vatican II's Nostra Aetate (§3) explicitly references the Abrahamic kinship between Christians, Jews, and Muslims — the latter claiming Ishmael as their patriarchal ancestor — calling for fraternal esteem grounded precisely in this shared Abrahamic root.
For Today
For contemporary Catholics, this genealogy of people who seem peripheral to "the story" invites a profound examination of conscience regarding who we consider spiritually peripheral. The detailed naming of Ishmael's sons — none of whom are in the covenant line, all of whom are remembered by God — challenges any tendency to treat the spiritual lives of people outside our immediate religious community as irrelevant or null. God keeps His word to Hagar in the desert: the twelve princes arrive exactly as promised.
More concretely, this passage speaks to Catholics who feel themselves to be "Ishmaels" — born of complicated circumstances, carrying the weight of being the child of the second wife, the outsider in the family of faith, the one who doesn't quite fit the expected mold of holiness. God names Ishmael's sons. God counts Ishmael's years. God gathers him to his people with the same reverent formula used for the great patriarchs. No person created in the image of God is too marginal for divine remembrance. In parish life, in family life, in the care of migrants and those on the peripheries — whom Pope Francis in Evangelii Gaudium (§49) calls the privileged recipients of the Gospel — this passage is a quiet summons to imitate God's comprehensive gaze.
