Numbers 9:15-17

15And on the day that the tabernacle was set up, the cloud covered the tabernacle of the tent of testimony; and at even it was upon the tabernacle as the appearance of fire, until the morning.

16So it was continually: the cloud covered it, and at night it was as the appearance of fire.

17And when the cloud rose from the tent, then the children of Israel journeyed; and at the place where the cloud stood still, there the children of Israel encamped.
