TSK · Exodus 40:38

the pillar of cloud by day, and the pillar of fire by night, didn't depart from before the people.

So it was continually. The cloud covered it, and the appearance of fire by night.

For I have not lived in a house since the day that I brought up the children of Israel out of Egypt, even to this day, but have moved around in a tent and in a tabernacle.

He spread a cloud for a covering, fire to give light in the night.
