Numbers 9:15-17

15On the day that the tabernacle was set up, the cloud covered the tabernacle – the tent of the testimony – and from evening until morning there was a fiery appearance over the tabernacle.

16This is the way it used to be continually: The cloud would cover it by day, and there was a fiery appearance by night.

17Whenever the cloud was taken up from the tabernacle, then after that the Israelites would begin their journey; and in whatever place the cloud settled, there the Israelites would make camp.
