Sarah the Prophet Saw What Ishmael Was Doing and Acted

The Feast With a Crack in It

The house should have been full of relief. Abraham was one hundred years old. Sarah had nursed a son everyone had called impossible. The old ache of barrenness had been answered with a child named Laughter. They held a feast on the day Isaac was weaned.

Then Sarah looked at Ishmael.

Genesis 21:9 gives one dangerous word for what she saw: metzachek. The root is the same as Isaac's name, which comes from laughter. The verb could mean laughing, playing, mocking, or something more transgressive. In the Hebrew text, whatever Ishmael was doing gets compressed into that single ambiguous word. Targum Jonathan on Genesis 21, the ancient Aramaic translation from the land of Israel compiled between the 4th and 7th centuries CE, closes the ambiguity: Ishmael was practicing strange worship, bowing toward idols at the feast where the covenant child was being celebrated.

The problem was not sibling rivalry. It was the possibility that Isaac, the child of the promise, would grow up in a house where worship was treated as a game.

Why Sarah Was a Prophetess

When Abraham hesitates at Sarah's demand to expel Hagar and Ishmael, God tells him to listen to Sarah's voice. In the Hebrew text of Genesis 21:12, that is all God says: hearken to her voice. Targum Jonathan adds a title. God tells Abraham to listen "because she is a prophetess." The Hebrew conveys authority. The Targum explains its source.

The Babylonian Talmud, tractate Megillah 14a, lists seven prophetesses of Israel: Sarah, Miriam, Deborah, Hannah, Abigail, Huldah, and Esther. Sarah is first. The Talmud's list preserves a tradition that her authority was not simply that of a wife or matriarch. She held a prophetic rank. Her commands carried the weight of revelation, not merely of domestic preference.

What Sarah saw at the feast was not a mother's suspicion. It was a prophet's perception. She looked at what Ishmael was doing and understood its consequences for the covenant line in a way Abraham, standing in the same room, did not. God's instruction to Abraham to follow her was an acknowledgment that her vision was accurate.

The Water That Dried Up in the Desert

The expulsion that followed was brutal regardless of its theological justification. Abraham rose early, gave Hagar bread and a bottle of water on her shoulders, and sent her and Ishmael into the wilderness of Beersheba. The Book of Jubilees, a Second Temple Jewish text composed around the second century BCE, keeps the account spare and merciless: they wandered, the water gave out, and Ishmael began to die.

Targum Jonathan on Genesis 21:15 adds a reason for the water's failure. When they came to the entrance of the desert, Hagar and Ishmael "remembered to wander after strange worship." The water that God had allowed them to carry became unavailable when they turned back toward the idols of Egypt. The Aramaic draws the causal link tightly: the idolatry and the thirst are not sequential misfortunes. One brings the other.

Ishmael collapses. His flesh withers. Hagar carries him as far as she can and then puts him down under a bush and walks away, because she cannot watch him die. She calls out to "the Fear of his father," the Targum's phrase for the God of Abraham, and weeps. What the Targum calls "the Fear of his father" is the same God who had spoken to her in the desert before, who had found her by the spring and given her a promise about Ishmael's future. She is calling on a God she has met before, in precisely this kind of extremity.

What the Well Revealed

The divine messenger who answers her is consistent with the logic the Targum has been building throughout. Sarah saw truly. The expulsion was necessary. But the necessity of the expulsion did not mean Hagar and Ishmael were abandoned. God opens Hagar's eyes, she sees a well that was already there, and she fills the water skin and gives Ishmael water. The well was not created in that moment. It had been there. What was given was the sight to find it.

The two threads of the story hold their tension without resolving it. Sarah was right about the threat. God was attentive to the threatened. The covenant line required protection, and Hagar's son required rescue. These were not contradictory. They were simultaneous acts of a God who does not choose between categories of persons when he acts.
