Genesis 32:22: The most precisely sited sentence in his life, and he sends everyone over it ahead of him

"The same night he arose and took his two wives, his two female servants, and his eleven children, and crossed the ford of the Jabbok." Everything about this verse is exact except the thing a map would most like to know. The night, the two wives, the two maidservants, the eleven children, the ford, the river: the writer counts the household over the water one group at a time. Which ford, he does not say, and there are several along the lower Jabbok where the bed widens and a man could take children across in the dark. The river is the Zarqa, and it is the reason this stretch of country matters. It comes out of the desert near Amman, swings north and then west, and cuts a gorge down to the Jordan — a real boundary, deep enough that the road either crosses it or goes round. Numbers and Deuteronomy use it as a border again and again: the Jabbok was the frontier of the Ammonites, and Sihon's kingdom ran to it. The map draws the river and not a dot. The sources file one representative point for the name, in the middle reach, and it is a point standing for a line; the course itself is what the verse is about, so the water is drawn as ground and the point is a ring on it. The crossing is put at the lower bed, between the two mounds of the next two pages. Then the sentence everything turns on: he took them over, sent across everything he had, and was left alone. The wrestling, the hip, the new name and the sunrise all happen on the bank he has just cleared of his own family, and the place is named at 32:30 for the face he sees there.
