Exodus 40:29-33

29And 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. 30And he set the laver between the tent of the congregation and the altar, and put water there, to wash with . 31And Moses and Aaron and his sons washed their hands and their feet from it: 32When they went into the tent of the congregation, and when they came near to the altar, they washed; as the LORD commanded Moses. 33And he reared up the court all around the tabernacle and the altar, and set up the hanging of the court gate. So Moses finished the work.
