Numbers 9:15-17

15On 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.

16It remained that way continuously: the cloud would cover it, appearing like fire at night.

17Whenever the cloud was lifted up above the tent, the Israelites would set out; at the place where the cloud stopped, there the Israelites camped.
