Numbers 9:17-19

Whenever the cloud was taken up from above the tabernacle, after that the children of Israel would journey; and in the place where the cloud settled, there the children of Israel would pitch their tents. At the command of the LORD the children of Israel would journey, and at the command of the LORD they would camp; as long as the cloud stayed above the tabernacle they remained encamped. Even when the cloud continued long, many days above the tabernacle, the children of Israel kept the charge of the LORD and did not journey.
