Exodus 40:33-38

33Then Moses set up the courtyard around the tabernacle and altar and put up the curtain at the entrance to the courtyard. And so Moses finished the work.

The Glory of the LORD 34Then the cloud covered the tent of meeting, and the glory of the LORD filled the tabernacle.

35Moses could not enter the tent of meeting because the cloud had settled on it, and the glory of the LORD filled the tabernacle. 36In all the travels of the Israelites, whenever the cloud lifted from above the tabernacle, they would set out; 37but if the cloud did not lift, they did not set out—until the day it lifted. 38So 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.
