For the cloud of Adonai was on the Tabernacle by day and a fire was there by night, in the sight of all the house of Israel throughout all their journeys.
Since the day that I brought up the children of Israel from Egypt to this day I have not dwelt in a house, but have been moving about in a tent, even in a tabernacle.
Adonai went before them in a pillar of cloud by day to lead the way and in a pillar of fire by night to give them light. So they could travel both day and night.
On the day the Tabernacle was erected, the cloud covered the Tabernacle. By evening until morning, the cloud above the Tent of Testimony had an appearance like fire.
