Genesis 21:14-18 describes Hagar carrying Ishmael on her shoulder, laying "the child" under a shrub, and being told to lift up "the lad" — infant language. But Genesis 17:24-25 plus Genesis 21:5-9 has Ishmael at thirteen when circumcised and Isaac weaned (age 2-3) before the abandonment scene, which puts Ishmael somewhere between 14 and 17 years old. A teenager doesn't ride on the shoulder.
Proposed answers
People have answered this in several ways; GEBible presents them as equal peers.
14Abraham rose up early in the morning, and took bread and a container of water, and gave it to Hagar, putting it on her shoulder; and gave her the child, and sent her away. She departed, and wandered in the wilderness of Beersheba.15The water in the container was spent, and she put the child under one of the shrubs.16She went and sat down opposite him, a good way off, about a bow shot away. For she said, “Don’t let me see the death of the child.” She sat opposite him, and lifted up her voice, and wept.17God heard the voice of the boy. The angel of God called to Hagar out of the sky, and said to her, “What troubles you, Hagar? Don’t be afraid. For God has heard the voice of the boy where he is.18Get up, lift up the boy, and hold him with your hand. For I will make him a great nation.”
24Abraham was ninety-nine years old when he was circumcised in the flesh of his foreskin.25Ishmael, his son, was thirteen years old when he was circumcised in the flesh of his foreskin.
5Abraham was one hundred years old when his son, Isaac, was born to him.6Sarah said, “God has made me laugh. Everyone who hears will laugh with me.”7She said, “Who would have said to Abraham that Sarah would nurse children? For I have borne him a son in his old age.”8The child grew and was weaned. Abraham made a great feast on the day that Isaac was weaned.9Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, mocking.
What follows is one scholar’s way of reading this disagreement— a critical-historical view that often concludes the texts genuinely disagree. It draws on the peer-reviewed sources listed below and stands as one position among the answers above, presented for transparency, not as GEBible’s position.
How critical scholarship weighs this: Leans toward a genuine contradiction
This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.
The tension here is arithmetic before it is literary, and the arithmetic is unforgiving. Genesis 16:16 (P) dates Ishmael's birth to Abraham's eighty-sixth year. Genesis 17:24-25 (P) fixes Ishmael's age at thirteen when he is circumcised, in the year Abraham is ninety-nine — the same year Isaac is announced and conceived (Gen 17-18). Genesis 21:5 (P) then dates Isaac's birth to Abraham's hundredth year, which makes Ishmael fourteen at the moment Isaac is born. The expulsion in Genesis 21:8-9 follows the weaning feast, and weaning in the ancient world commonly occurred around ages two to three (2 Maccabees 7:27 attests a three-year nursing period in Jewish tradition, though the general claim rests on broader comparative data rather than that single verse). Adding two or three years to Ishmael's fourteen places him at roughly sixteen or seventeen when Hagar carries him into the wilderness — and the harmonizer must reconcile that figure with a scene that consistently speaks of a small child.
The vocabulary of Genesis 21:14-18 (E) does not cooperate. Hagar carries the boy alongside bread and a skin of water; she "casts" (Hebrew *wattašlēk*, the verb used for discarding objects) the child under a shrub (21:15); she sits "a bowshot away" so as not to watch "the death of the child" (*ha-yeled*, 21:16); and the angel commands her to "lift up the lad" (*śĕʾî ʾet-ha-naʿar*) and "hold him fast with your hand" (21:18). The noun *yeled* most naturally denotes a young child, and the physical helplessness — being placed, being cast, being lifted, being held by the hand — reads as infant care, not the conduct of a strapping teenager who in 21:20 immediately becomes a self-sufficient archer dwelling in the wilderness.
The strongest apologetic response, advanced by Victor Hamilton in NICOT and Kenneth Mathews in NAC, is grammatical. The *waw* before "the child" in 21:14 may be read so that Abraham placed *the bread and water* on Hagar's shoulder and then gave her the child as a separate act; the Masoretic syntax permits this, and the NRSV and NIV render it accordingly. The defense is legitimate as far as it goes — the LXX, by contrast, reads as though the child too was set on the shoulder, καὶ ἐπέθηκεν ἐπὶ τὸν ὦμον αὐτῆς... καὶ τὸ παιδίον, and some translators evidently understood the boy to be carried. But the syntactic fix rescues only the single detail of the shoulder. It does nothing for the casting, the abandonment under the bush, the maternal vigil over an expected death, or the repeated infant-coded verbs. The texture of the whole pericope, not one ambiguous conjunction, is what conflicts with the chronology.
The critical explanation is source-critical. The chronological framework (16:16; 17:24-25; 21:5) belongs to the Priestly writer, who is meticulous about ages and dates. The wilderness scene (21:8-21) is classically assigned to E, which preserves an independent tradition of Hagar and a young child — a doublet of the earlier Hagar narrative in Genesis 16 (J), where she flees before Ishmael is even born. Westermann, Friedman, and Baden all observe that E's Hagar story pictures Ishmael as a small boy and was never composed to harmonize with P's numbers. The redactor who stitched the Priestly chronology onto the older Elohistic legend left the seam exposed. Nahum Sarna, working within a more conservative Jewish framework, still concedes the difficulty and notes the rabbinic discomfort that produced midrashic attempts to read Ishmael as gravely ill (hence carried) rather than merely young. That midrashic move is itself evidence that ancient readers felt the same friction the modern critic identifies.
The verdict turns on what one is willing to grant. If the only datum at issue were the shoulder, the grammar would dissolve the problem. But the conflict is between P's explicit ages — yielding a sixteen- or seventeen-year-old — and E's portrayal of an abandoned toddler cast weeping under a bush, and no retranslation reconciles an adolescent archer with a child whose mother places him in the shade and walks away to avoid watching him die.
Where the critical reading lands: genuine contradiction rooted in the combination of Priestly chronology with an older Elohistic narrative.
