Whenever the cloud was lifted from above the Tent, the Israelites would set out, and wherever the cloud settled, there the Israelites would camp. / At the LORD’s command the Israelites set out, and at the LORD’s command they camped. As long as the cloud remained over the tabernacle, they remained encamped. / Even when the cloud lingered over the tabernacle for many days, the Israelites kept the LORD’s charge and did not set out.
