Exodus 40:29-33

29And he set the altar of burnt-offering at the door of the tabernacle of the tent of meeting, and offered upon it the burnt-offering and the meal-offering; as Jehovah commanded Moses. 30And he set the laver between the tent of meeting and the altar, and put water therein, wherewith to wash. 31And Moses and Aaron and his sons washed their hands and their feet thereat; 32when they went into the tent of meeting, and when they came near unto the altar, they washed; as Jehovah commanded Moses. 33And he reared up the court round about the tabernacle and the altar, and set up the screen of the gate of the court. So Moses finished the work.
