Numbers 9:20

At the commandment of the LORD the children of Israel journeyed, and at the commandment of the LORD they pitched: as long as the cloud abode upon the tabernacle they rested in their tents.

And when the cloud tarried long upon the tabernacle many days, then the children of Israel kept the charge of the LORD, and journeyed not.

And so it was, when the cloud abode from even unto the morning, and that the cloud was taken up in the morning, then they journeyed: whether it was by day or by night that the cloud was taken up, they journeyed.

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.
