Numbers 9:15-17

Now on the day that the tabernacle was erected the cloud covered the tabernacle, the tent of the testimony, and in the evening it was like the appearance of fire over the tabernacle, until morning. So it was continuously; the cloud would cover it by day, and the appearance of fire by night. Whenever the cloud was lifted from over the tent, afterward the sons of Israel would then set out; and in the place where the cloud settled down, there the sons of Israel would camp.
