Exodus 13:20-22

20And athey moved on from Succoth and encamped at Etham, on the edge of the wilderness. 21And bthe Lord went before them by day in a pillar of cloud to lead them along the way, and by night in a pillar of fire to give them light, that they might travel by day and by night. 22The pillar of cloud by day and the pillar of fire by night did not depart from before the people.
