17. And when the cloud that covered the tabernacle was taken up, then the children of Israel marched forward: and in the place where the cloud stood still, there they camped.
18. At the commandment of the Lord they marched, and at his commandment they pitched the tabernacle. All the days that the cloud abode over the tabernacle, they remained in the same place:
19. And if it was so that it continued over it a long time, the children of Israel kept the watches of the Lord, and marched not,
20. For as many days soever as the cloud stayed over the tabernacle. At the commandment of the Lord they pitched their tents, and at his commandment they took them down.
21. If the cloud tarried from evening until morning, and immediately at break of day left the tabernacle, they marched forward: and if it departed after a day and a night, they took down their tents.
