Exodus 40:36-38

New International Version - UK

³⁶ In all the travels of the Israelites, whenever the cloud lifted from above the tabernacle, they would set out; ³⁷ but if the cloud did not lift, they did not set out – until the day it lifted. ³⁸ So the cloud of the Lord was over the tabernacle by day, and fire was in the cloud by night, in the sight of all the Israelites during all their travels.
