Moses spent the first forty years of his life as an Egyptian prince. He spent the next forty years as a shepherd in the wilderness. The map before you shows that wilderness — the vast, empty Negev and southern desert between Canaan and Sinai. This is the terrain Moses crossed when he fled Egypt, and the terrain he covered for forty years tending the flocks of his father-in-law Jethro, priest of Midian.

The flight from Egypt is described in Exodus 2:15 with the same spare economy as the rest of Moses' early story: "But Moses fled from the face of Pharaoh, and dwelt in the land of Midian." He came to a well — find 'Beer-Sheba' at the top of the map as a reference point, then trace your mind south and east toward the Midian territory. At the well, he encountered seven daughters of a Midianite priest being driven away by shepherds. Moses defended them, watered their flocks, and was invited home. He married Zipporah, had a son, and settled into the rhythms of a shepherd's life.

Forty years passed. He was eighty years old. He had long since stopped thinking of himself as the deliverer of Israel. The man who had "supposed his brethren would have understood how that God by his hand would deliver them" (Acts 7:25) had been reduced to complete anonymity — a shepherd in a foreign wilderness, known only to his wife's family. And then he led the flock "to the backside of the desert" — deep into the southern wilderness shown on this map — and came to the mountain of God.

The bush was burning but not consumed. Moses turned aside to see. And God spoke from the bush: "I am the God of thy father, the God of Abraham, the God of Isaac, and the God of Jacob." He had seen Israel's affliction. He had heard their cry. He was coming down to deliver them. And Moses — the man who had fled Egypt as a failed deliverer, who had spent forty years in obscurity — was the one God had chosen to go back. His objection was immediate: "Who am I, that I should go unto Pharaoh?" (Exodus 3:11). God's answer was the only answer that matters: "Certainly I will be with thee."
