Numbers 9:18-23

18 At the command of the LORD the people of Israel set out, and at the command of the LORD they encamped; as long as the cloud rested over the tabernacle, they remained in camp.
19 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.
20 Sometimes the cloud was a few days over the tabernacle, and according to the command of the LORD they remained in camp; then according to the command of the LORD they set out.
21 And sometimes the cloud remained from evening until morning; and when the cloud was taken up in the morning, they set out, or if it continued for a day and a night, when the cloud was taken up they set out.
22 Whether it was two days, or a month, or a longer time, that the cloud continued over the tabernacle, abiding there, the people of Israel remained in camp and did not set out; but when it was taken up they set out.
23 At the command of the LORD they encamped, and at the command of the LORD they set out; they kept the charge of the LORD, at the command of the LORD by Moses.
