Genesis 17:18

Genesis 17:18, in plain English

Abraham makes his own request, asking God to bless Ishmael—the son he already has—suggesting he's hoping that perhaps this could fulfill the covenant promise.

Why it's here

Abraham already has a son, Ishmael, born through Hagar. He loves this boy. When God speaks of 'your son' and blessing, maybe Abraham is thinking, 'Couldn't it be Ishmael? Couldn't my covenant son be the one I already have?' He's not rejecting God's plan, but he's advocating for his firstborn, hoping his existing family can be part of the answer.

Who's speaking

Abraham makes his request known to God

Where it sits in the story

This shows Abraham's love for Ishmael and his desire to see him blessed. But it also shows he's still hoping there's another way, a way that doesn't require the impossible. God loves this too—He's going to bless Ishmael—but He's also going to clarify that the covenant child will be different.

The scholarly reading

Abraham intercedes for Ishmael, seeking God's blessing upon the son he has already fathered and asking whether the covenant promises might be channeled through him instead.

Language and setting

Abraham's plea 'O that Ishmael might live before you' (lu yishmar Yishmael lefanecha) employs the conditional particle 'lu'—expressing unrealized desire. He has already invested emotionally and genealogically in Ishmael; the prospect of Isaac seems impossible, yet more importantly, seems to supersede Ishmael. This reveals Abraham's practical wisdom and paternal affection, but also his assumption that the promise might be flexible regarding through whom it flows.

Voice

Abraham, pleading with God on behalf of his existing son

Significance

This request demonstrates Abraham's limitation: he cannot yet fully relinquish his own solution to the promise (Ishmael). The covenant theology that emerges from this passage insists that God—not human ingenuity—determines the line of promise. Later, Romans 9:7-8 will use this moment to argue that the 'seed of Abraham' is constituted through promise, not through flesh.

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!”

19But God replied, “Your wife Sarah will indeed bear you a son, and you are to name him Isaac. I will establish My covenant with him as an everlasting covenant for his descendants after him.

20As for Ishmael, I have heard you, and I will surely bless him; I will make him fruitful and multiply him greatly. He will become the father of twelve rulers, and I will make him into a great nation.

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.
