Numbers 9:19-22

19When the cloud remained over the tabernacle many days, then the Israelites obeyed the instructions of the Lord and did not journey.

20When the cloud remained over the tabernacle a number of days, they remained camped according to the Lord’s commandment, and according to the Lord’s commandment they would journey.

21And when the cloud remained only from evening until morning, when the cloud was taken up the following morning, then they traveled on. Whether by day or by night, when the cloud was taken up they traveled.

22Whether it was for two days, or a month, or a year, that the cloud prolonged its stay over the tabernacle, the Israelites remained camped without traveling; but when it was taken up, they traveled on.
