Exodus 40:34 (KJV)

And he put the altar of burnt offering by the door of the tabernacle of the tent of the congregation, and offered upon it the burnt offering and the meat offering; as the LORD commanded Moses.

And he set the laver between the tent of the congregation and the altar, and put water there, to wash withal.

And Moses and Aaron and his sons washed their hands and their feet thereat:

When they went into the tent of the congregation, and when they came near unto the altar, they washed; as the LORD commanded Moses.

And he reared up the court round about the tabernacle and the altar, and set up the hanging of the court gate. So Moses finished the work.

And Moses was not able to enter into the tent of the congregation, because the cloud abode thereon, and the glory of the LORD filled the tabernacle.

And when the cloud was taken up from over the tabernacle, the children of Israel went onward in all their journeys:

But if the cloud were not taken up, then they journeyed not till the day that it was taken up.

For the cloud of the LORD was upon the tabernacle by day, and fire was on it by night, in the sight of all the house of Israel, throughout all their journeys.
