Numbers 9:15-17

15Now on the day that the tabernacle was erected, the cloud [of God’s presence] covered the tabernacle, that is, the tent of the Testimony; and in the evening it was over the tabernacle, appearing like [a pillar of] fire until the morning.

16So it was continuously; the cloud covered it by day, and the appearance of fire by night.

17Whenever the cloud was lifted from over the tent (tabernacle), afterward the Israelites would set out; and in the place where the cloud stopped, there the Israelites would camp.
