Exodus 40:33-37

And he erected the courtyard all around the tabernacle and the altar, and hung up the curtain for the gate of the courtyard. So Moses finished the work. The Glory of the Lord

Then the cloud covered the tent of meeting, and the glory of the Lord filled the tabernacle.

And Moses was not able to enter the tent of meeting because the cloud had settled on it, and the glory of the Lord filled the tabernacle.

Throughout their journeys, whenever the cloud was taken up from over the tabernacle, the sons of Israel would set out;

but if the cloud was not taken up, then they did not set out until the day when it was taken up.
