Exodus 40:34

30 He placed the basin between the Tent of Meeting and the altar and put water in it for washing;

31 and from it Moses, Aaron, and his sons washed their hands and feet.

32 They washed whenever they entered the Tent of Meeting or approached the altar, just as the LORD had commanded Moses.

33 And Moses set up the courtyard around the tabernacle and the altar, and he hung the curtain for the entrance to the courtyard. So Moses finished the work.

34 Then the cloud covered the Tent of Meeting, and the glory of the LORD filled the tabernacle.

35 Moses was unable to enter the Tent of Meeting because the cloud had settled on it, and the glory of the LORD filled the tabernacle.

36 Whenever the cloud was lifted from above the tabernacle, the Israelites would set out through all the stages of their journey.

37 If the cloud was not lifted, they would not set out until the day it was taken up.

38 For 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 house of Israel through all their journeys.
