Genesis 20:18

Genesis 20:18, in plain English

The narrator explains that God had closed all the wombs in Abimelech's household because of Sarah—a sign of God's protection that was invisible until it was reversed. The story comes full circle.

Why it's here

This final verse reveals what was happening behind the scenes the whole time. God didn't just prevent Abimelech from touching Sarah; God also prevented any natural conception in his entire household. The infertility was God's way of keeping the situation from getting worse in hidden ways.

Where it sits in the story

This is the complete picture of God's protection. God was working on multiple levels—preventing Abimelech from sinning, protecting Sarah from violation, and now restoring fertility through Abraham's prayer. God's providence includes things we never see at the time. Abraham's fear made him miss how thoroughly God was already protecting the situation.

The scholarly reading

The narrator concludes by explaining that God had closed all the wombs in Abimelech's household specifically on account of Sarah's presence, and now healed them through Abraham's intercession.

Language and setting

The causal explanation 'on account of Abraham's wife Sarah' ('al-sippurei Sarai) reveals that the supernatural affliction was divinely imposed as a mechanism for enforcing Sarah's restoration and protecting the lineage. The closure of wombs (satam et-kol-rahem) represents a cosmic-level divine intervention preventing procreation within the household—a parallel to the barrenness afflicting Sarah herself (cf. 11:30). The Yahwistic narrative employs reproductive symbolism as the ultimate measure of divine blessing or curse, making fertility the covenantal sign.

Significance

This final verse crystallizes the episode's theological meaning: while Abraham's deception puts the covenant-lineage in jeopardy, divine providence employs supernatural means to preserve Sarah's integrity and ensure the promised progeny. The household fertility restoration through Abraham's intercession demonstrates that the patriarch, despite his failures, remains God's chosen instrument for blessing the nations—a principle foundational to the Abrahamic theology developed throughout the Hebrew Bible.

16And he said to Sarah, “See, I am giving your brother a thousand pieces of silver. It is your vindication before all who are with you; you are completely cleared.”

17Then Abraham prayed to God, and God healed Abimelech and his wife and his maidservants, so that they could again bear children—

18for on account of Abraham’s wife Sarah, the LORD had completely closed all the wombs in Abimelech’s household.
