Genesis 21:13

Genesis 21:13, in plain English

God also reassures Abraham about Ishmael's future. Even though Ishmael won't carry the main covenant, God promises to make him into a great nation because he's Abraham's offspring too.

Why it's here

This is important—God isn't discarding Ishmael. He's just clarifying the structure of the promise. Ishmael will be blessed. His descendants will be many. But his blessing and his nation will be separate from the covenant line that leads to Israel and to Christ. Abraham needs to hear this. He's giving up his firstborn from the household, but God is saying: I won't abandon Ishmael.

Who's speaking

God continues speaking to Abraham.

Where it sits in the story

Ishmael's line becomes the father of the Arab peoples. God blesses him, multiplies him, and keeps a covenant with him—but it's distinct from the Abrahamic covenant that flows through Isaac. God keeps promises to both, but in different ways.

The scholarly reading

God promises to bless Ishmael and make him into a great nation as well, because he too is Abraham's offspring, ensuring that expulsion from the covenant does not mean abandonment by God.

Language and setting

The conjunction 'but' (vgam, וְגַם) introduces a crucial divine mercy: Ishmael will not perish in the wilderness, and his expulsion from the covenant promise does not nullify God's providential care. The phrase 'I will make a nation of the slave woman's son' (eth-ben-hashiphchah gam-assimenu legoiy, אֶת־בֶּן־הַשִּׁפְחָה גַּם־אֲשִׂימֶנּוּ לְגוֹי) echoes the original covenant promise to Abraham (12:2), suggesting that Ishmael receives a secondary but genuine blessing.

Voice

God, extending mercy beyond the covenant proper

Significance

This verse introduces a crucial theological principle: God's particular election does not preclude God's general providence. Ishmael becomes the ancestor of the Ishmaelite peoples (later identified with Arab tribes), and his story parallels the covenant narrative while remaining distinct from it. Islamic tradition later identifies Ishmael as Abraham's covenant heir—a reinterpretation that testifies to the significance of this promise.

11Now this matter distressed Abraham greatly because it concerned his son Ishmael.

12But God said to Abraham, “Do not be distressed about the boy and your maidservant. Listen to everything that Sarah tells you, for through Isaac your offspring will be reckoned.

13But I will also make a nation of the slave woman’s son, because he is your offspring.”

14Early in the morning, Abraham got up, took bread and a skin of water, put them on Hagar’s shoulders, and sent her away with the boy. She left and wandered in the Wilderness of Beersheba.

15When the water in the skin was gone, she left the boy under one of the bushes.

Read all of Genesis 21 — The promised son arrives — and Sarah laughs again, this time with joy. But the arrival of one son means the departure of another.
