Numbers 9:15-17

15On the day that the tabernacle was set up, the cloud covered the tabernacle, the tent of the testimony. And at evening it was over the tabernacle like the appearance of fire until morning.

16So it was always: the cloud covered it by day and the appearance of fire by night.

17And whenever the cloud lifted from over the tent, after that the people of Israel set out, and in the place where the cloud settled down, there the people of Israel camped.
