Numbers 9:20-22 Modern English Version (MEV)
20 When the cloud remained a few days over the tabernacle, according to the commandment of the Lord they dwelt in their tents, and according to the commandment of the Lord they journeyed. 21 When the cloud dwelt from evening until morning and the cloud was lifted up in the morning, then they journeyed. Whether it was by day or by night that the cloud was lifted up, they journeyed. 22 Whether it was two days, or a month, or a long time that the cloud dwelt over the tabernacle, the children of Israel dwelt in their tents and did not journey. But when it was lifted up they journeyed.
