Numbers 9:15-18

On the day the tabernacle was set up, the cloud covered the tabernacle, the tent of the testimony, and it appeared like fire above the tabernacle from evening until morning. It remained that way continuously: the cloud would cover it, appearing like fire at night. Whenever the cloud was lifted up above the tent, the Israelites would set out; at the place where the cloud stopped, there the Israelites camped. At the LORD’s command the Israelites set out, and at the LORD’s command they camped. As long as the cloud stayed over the tabernacle, they camped.
