Numbers 9:15-18

On the day the Holy Tent, the Tent of the Agreement, was set up, a cloud covered it. From dusk until dawn the cloud above the Tent looked like fire. The cloud stayed above the Tent, and at night it looked like fire. When the cloud moved from its place over the Tent, the Israelites moved, and wherever the cloud stopped, the Israelites camped. So the Israelites moved at the LORD’s command, and they camped at his command. While the cloud stayed over the Tent, they remained camped.
