Numbers 9:22

Whether the cloud lingered for two days, a month, or longer, the Israelites camped and did not set out as long as the cloud remained over the tabernacle; but when it was lifted, they would set out.

Or whether it were two days, or a month, or a year, that the cloud tarried upon the tabernacle, remaining thereon, the children of Israel abode in their tents, and journeyed not: but when it was taken up, they journeyed.
