Exodus 13:18-22

but God led the people about, through the way of the wilderness of the Red sea: and the children of Israel went up harnessed out of the land of Egypt. And Moses took the bones of Joseph with him: for he had straitly sworn the children of Israel, saying, God will surely visit you; and ye shall carry up my bones away hence with you. And they took their journey from Succoth, and encamped in Etham, in the edge of the wilderness. And the LORD went before them by day in a pillar of a cloud, to lead them the way; and by night in a pillar of fire, to give them light; to go by day and night: he took not away the pillar of the cloud by day, nor the pillar of fire by night, from before the people.
