Numbers 9:19

16 So it was always: the cloud covered it, and the appearance of fire by night.

17 Whenever the cloud was taken up from over the Tent, then after that the children of Israel journeyed: and in the place where the cloud abode, there the children of Israel encamped.

18 At the commandment of Yahweh the children of Israel journeyed, and at the commandment of Yahweh they encamped: as long as the cloud abode on the tent they remained encamped.

19 When the cloud stayed on the tent many days, then the children of Israel kept the charge of Yahweh, and didn`t travel.

20 Sometimes the cloud was a few days on the tent; then according to the commandment of Yahweh they remained encamped, and according to the commandment of Yahweh they journeyed.

21 Sometimes the cloud was from evening until morning; and when the cloud was taken up in the morning, they journeyed: or [if it continued] by day and by night, when the cloud was taken up, they journeyed.

22 Whether it were two days, or a month, or a year, that the cloud stayed on the tent, abiding thereon, the children of Israel remained encamped, and didn`t travel; but when it was taken up, they traveled.
