Exodus 40:30-35

30He placed the basin between the tent of meeting and the altar and put water in it for washing, 31and Moses and Aaron and his sons used it to wash their hands and feet.

32They washed whenever they entered the tent of meeting or approached the altar, as the LORD commanded Moses.

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.
