Genesis 21:21: Two countries, a marriage, and no road between them the text will name

"He lived in the wilderness of Paran, and his mother took a wife for him from the land of Egypt." This is where Abraham's story stops being the only one on the page. Ishmael is grown, living in the desert and good with a bow, and his mother goes and finds him a wife — the only marriage in Genesis arranged by a woman, and she arranges it out of her own country. Hagar is an Egyptian; the household brought her back from Egypt in Genesis 12 as part of the payment for a lie. Three chapters after being put out with a skin of water, she is fetching her son a wife from home. The two names on this map are both countries rather than towns, so both are drawn as rings at the point the sources use to stand for a whole region, and the two rings are two hundred and fifty miles apart. Paran is the wilderness of the central Negev and the eastern Sinai — the same country Israel will spend a generation crossing, and Abraham never sets foot in it. Egypt is anchored where every source anchors it, at Heliopolis, under what is now Cairo. The journey between them is the point of the sentence and is given no road at all. Genesis will spend a whole chapter on the servant's ride to Mesopotamia to fetch Rebekah — the camels, the gifts, the well, the conversation with the family — and it gives Ishmael's marriage eleven words and no itinerary. So the line here is a ghost: it says that somebody went, and it does not claim to know how. What comes of it is a nation. Genesis 25 lists twelve princes descended from Ishmael, settled from Havilah to Shur, and the last thing it says of him is that he lived over against all his kinsmen. His father's map and his do not overlap again until the two of them stand at the same grave.
