Sarah the Prophet Saw What Ishmael Was Doing and Acted

The word that splits the household of Abraham is ambiguous. Genesis 21:9 says Sarah "saw the son of Hagar the Egyptian, whom she had borne to Abraham, playing." The Hebrew word for playing, metzachek, shares a root with the name Isaac. It can mean laughing, playing, mocking, or something worse. The tradition seized on that ambiguity and never let it go.

Targum Jonathan on Genesis 21, composed in the land of Israel between the 4th and 7th centuries CE, resolves the ambiguity in the most decisive way possible. What Sarah saw was idol worship. Ishmael was not playing. He was performing religious acts directed at an idol, and Sarah, described in the Targum as a prophet, understood immediately what she was witnessing and what it would cost her son Isaac if the two boys remained together.

The Miracle That Opened the Story

The Targum on Genesis 21 begins before the idol appears. It begins with a miracle that mirrors a previous act of Abraham's. God remembered Sarah, the Torah says (Genesis 21:1), and she conceived. The Targum specifies that God performed for Sarah the same healing that Abraham had prayed for on behalf of Abimelech in Genesis 20. Abimelech's household had been struck barren because he had taken Sarah. Abraham prayed, and the barrenness was lifted. Now God performs that same reversal, in the opposite direction, for Sarah herself.

This parallelism is important. The healing of Sarah is connected to the healing Abraham secured for someone else. The 2,921 texts of Midrash Rabbah read this as a principle of divine reciprocity: righteousness returns to its source. Abraham's intercession for Abimelech, even after Abimelech had endangered Sarah, created a spiritual account. God drew on that account when Sarah needed what she had prayed for over decades.

What Sarah's Prophetic Vision Showed Her

The Targum describes Sarah not merely as an attentive mother but as a prophet. This designation is significant. The 3,205 texts of Midrash Aggadah are careful about the category of prophecy. It is not intuition or maternal instinct. It is a specific form of divine communication in which information is transmitted that the recipient could not have reached by ordinary observation.

What Sarah saw, the Targum says, was not merely that Ishmael was playing with an idol. She saw the theological consequence of allowing the two boys to develop together. Isaac would absorb the practice, or be mocked for refusing it, or be subtly shaped by proximity to someone who treated divine worship as flexible. Sarah's prophetic vision was not only about what Ishmael was doing in that moment. It was about what would happen over years if nothing was done about it now.

Abraham's Distress and What Caused It

The Torah says Abraham was greatly distressed by Sarah's demand that Hagar and Ishmael be sent away. The Targum specifies what caused the distress: it was because of the boy, not because of Hagar. This is a small distinction that carries significant weight. Abraham's grief was paternal, not domestic. He was not mourning a household arrangement. He was mourning a son.

The Talmudic tractate Sotah 12a preserves a tradition about the relative prophetic status of Sarah and Abraham. It says directly that Sarah was a greater prophet than Abraham. God's instruction to Abraham to listen to Sarah's voice (Genesis 21:12) is read in this tradition as a divine confirmation of prophetic hierarchy. Sarah saw something Abraham had not seen, or had seen and was unable to act on because of paternal love. God tells Abraham to defer to the prophet whose vision was clearer.

Hagar and Ishmael in the Wilderness

The expulsion of Hagar and Ishmael into the wilderness is one of the most emotionally difficult scenes in Genesis. The Targum does not soften it. Hagar walks into the desert with a child and a single container of water. When the water runs out, she puts Ishmael under a bush and moves away because she cannot watch him die.

An angel calls to Hagar by name, the same divine attention she received in Genesis 16, and shows her a well she had not seen. The water, according to the midrashic tradition preserved in the Legends of the Jews, was always there. It was Hagar's anguish that prevented her from seeing it. The Targum adds that God opened her eyes, and the well appeared. The same prophetic capacity that Sarah had used to see Ishmael's idol worship, Hagar now needed to see the water that would keep her son alive.

The Targum holds both women as prophets, both mothers as correct in what they saw, both stories as necessary for the larger narrative to make sense. Sarah's vision drove the expulsion. Hagar's opened eyes allowed the survival. The covenant that would run through Isaac required the separation that Sarah saw. The life of Ishmael, who would also fulfill a divine promise, required the water that God showed to Hagar. The Targum preserves the full story of both, and does not ask the reader to choose which mother's vision was more important.
