Numbers 9:19-22

19And when the cloud tarried upon the tabernacle many days, then the children of Israel kept the charge of Jehovah, and journeyed not. 20And sometimes the cloud was a few days upon the tabernacle; then according to the commandment of Jehovah they remained encamped, and according to the commandment of Jehovah they journeyed. 21And sometimes the cloud was from evening until morning; and when the cloud was taken up in the morning, they journeyed: or if it continued by day and by night, when the cloud was taken up, they journeyed. 22Whether it were two days, or a month, or a year, that the cloud tarried upon the tabernacle, abiding thereon, the children of Israel remained encamped, and journeyed not; but when it was taken up, they journeyed.
