Genesis 17:16

Genesis 17:16, in plain English

God promises to bless Sarah and give Abraham a son through her—Sarah will become the mother of nations, and kings will descend from her.

Why it's here

Here it is—the direct promise about the son Abraham has been waiting for. But it's Sarah who will bear him. Sarah, who has been infertile her whole life, is about to become pregnant at an age when it's medically impossible. God is not just giving Abraham a son; He's making Sarah a matriarch, a mother of nations, not just of one child but of entire peoples.

Who's speaking

God makes the explicit promise about Sarah and the coming son

Where it sits in the story

This is the pivot point for Sarah's life. She moves from being a woman defined by infertility to being the mother of all that God promises. Her faith will be tested, but ultimately she becomes the spiritual mother not just of Israel but of all who believe, as Paul later explains.

The scholarly reading

God promises to bless Sarah specifically and will give her a son with Abraham, making her the mother of nations and ancestress of kings—elevating her to parallel covenantal prominence.

Language and setting

The divine blessing directed at Sarah (veberachtiha) is unusual; typically in Genesis, blessing flows from God through male figures. Here Sarah receives blessing directly, and she will bear the son of promise. The phrase 'mother of nations' (em goyim) mirrors Abraham's 'father of many nations,' indicating parity of function. The Reformation commentator Matthew Henry observed that Sarah's faith is subsequently tested more severely than Abraham's—she must believe while experiencing barrenness and age.

Voice

God, blessing Sarah and promising the son through her specifically

Significance

This promise directly contradicts the evidence: Sarah is ninety years old (revealed in verse 17) and long past childbearing. The covenant's fulfillment will depend upon Sarah's consent and faith, making her an active partner in God's promise rather than merely a biological vessel.

14But if any male is not circumcised, he will be cut off from his people; he has broken My covenant.”

15Then God said to Abraham, “As for Sarai your wife, do not call her Sarai, for her name is to be Sarah.

16And I will bless her and will surely give you a son by her. I will bless her, and she will be the mother of nations; kings of peoples will descend from her.”

17Abraham fell facedown. Then he laughed and said to himself, “Can a child be born to a man who is a hundred years old? Can Sarah give birth at the age of ninety?”

18And Abraham said to God, “O that Ishmael might live under Your blessing!”

Read all of Genesis 17 — God changes Abram's name to Abraham — father of many. A permanent sign marks his body and his descendants forever.
