Numbers 9:18

On the day that the tabernacle was raised up, the cloud covered the tabernacle, even the Tent of the Testimony. At evening it was over the tabernacle, as it were the appearance of fire, until morning.

So it was continually. The cloud covered it, and the appearance of fire by night.

Whenever the cloud was taken up from over the Tent, then after that the children of Israel traveled; and in the place where the cloud remained, there the children of Israel encamped.

When the cloud stayed on the tabernacle many days, then the children of Israel kept the LORD’s command, and didn’t travel.

Sometimes the cloud was a few days on the tabernacle; then according to the commandment of the LORD they remained encamped, and according to the commandment of the LORD they traveled.

Sometimes the cloud was from evening until morning; and when the cloud was taken up in the morning, they traveled; or by day and by night, when the cloud was taken up, they traveled.
