Numbers 9:15-17

15On the day that Moses put up the Tent of Meeting, a cloud covered it. In the evening it became something like a fire over the Tent, until morning.

16It was like that all the time. The cloud covered it during the day. But at night, the cloud seemed to have fire in it.

17When the cloud went up from God's Tent, the Israelites started to travel. And when the cloud came down, the Israelites made their camp in that place.
