Numbers 9:18-22

At the command of the Lord the sons of Israel would set out, and at the command of the Lord they would camp; as long as the cloud settled over the tabernacle, they remained camped.

Even when the cloud lingered over the tabernacle for many days, the sons of Israel would comply with the Lord’s ordinance and not set out.

If sometimes the cloud remained a few days over the tabernacle, in accordance with the command of the Lord they remained camped. Then in accordance with the command of the Lord they set out.

If sometimes the cloud remained from evening until morning, when the cloud was lifted in the morning they would set out; or if it remained in the daytime and at night, whenever the cloud was lifted, they would set out.

Whether it was two days, a month, or a year that the cloud lingered over the tabernacle, staying above it, the sons of Israel remained camped and did not set out; but when it was lifted, they did set out.
