Numbers 9:15-18

Now 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. [Ex 13:21] So it was continuously; the cloud covered it by day, and the appearance of fire by night. Whenever 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. At the LORD’S command the Israelites would journey on, and at His command they would camp. As long as the cloud remained over the tabernacle they remained camped.
