Numbers 9:15-18

On 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. So it was always: the cloud covered it by day and the appearance of fire by night. And 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. At the command of the LORD the people of Israel set out, and at the command of the LORD they camped. As long as the cloud rested over the tabernacle, they remained in camp.
