Numbers 9:17-19

And whenever the cloud lifted from over the tent, after that the people of Israel set out, and in the place where the cloud settled down, there the people of Israel camped. At the command of the LORD the people of Israel set out, and at the command of the LORD they camped. As long as the cloud rested over the tabernacle, they remained in camp. Even when the cloud continued over the tabernacle many days, the people of Israel kept the charge of the LORD and did not set out.
