Numbers 9:15-17

15And on the day that the tabernacle was erected the cloud covered the tabernacle, namely, the tent of the testimony: and at evening there was upon the tabernacle as it were the appearance of fire, until the morning. 16So it was always: the cloud covered it by day, and the appearance of fire by night. 17And when the cloud was taken up from the tabernacle, then after that the children of Israel journeyed: and in the place where the cloud abode, there the children of Israel pitched their tents.
