What Does Genesis 21:17 Mean?

God was with the boy as he grew up. He lived in the desert and became an archer. While he was living in the Desert of Paran, his mother got a wife for him from Egypt. The summary of Ishmael's life is compressed into "God was with the boy as he grew up." The divine accompanying presence extended to the excluded firstborn in the desert. The one sent away from the covenant household is the one with whom God is as he grows, the promise made in verse 13 being fulfilled. God's care for the one outside the covenant inheritance is as real as His care for the covenant heir, though differently purposed.

The identification of Ishmael as "an archer" in the Desert of Paran corresponds to the prophetic characterization given before his birth in chapter 16:12: "a wild Donkey of a man; his hand will be against everyone." The desert life, the archery, the nomadic patterns, all correspond to the predicted character. The "God was with him" accompaniment does not change the character the prophecy described; it accompanies the character as it actually develops.

The mother's provision of an Egyptian wife connects Ishmael genealogically to her own origin: Hagar was Egyptian, and the wife she finds is also Egyptian. The Ishmaelite tribal genealogies show this Egyptian connection embedded in the family's identity. The people who become known as Ishmaelites will appear in chapter 37 as the caravan that carries Joseph to Egypt, the expelled firstborn's descendants returning into the covenant heir's story through the most unexpected route. The two lineages remain intertwined across the generations.
