Exodus 13:18-22

So God led the people around by way of the wilderness of the Red Sea. And the children of Israel went up in orderly ranks out of the land of Egypt. And Moses took the bones of Joseph with him, for he had placed the children of Israel under solemn oath, saying, “God will surely visit you, and you shall carry up my bones from here with you.” So they took their journey from Succoth and camped in Etham at the edge of the wilderness. And the LORD went before them by day in a pillar of cloud to lead the way, and by night in a pillar of fire to give them light, so as to go by day and night. He did not take away the pillar of cloud by day or the pillar of fire by night from before the people.
