Exodus 40:29-33

29And he 1set the altar of burnt offering in front of the doorway of the tabernacle of the tent of meeting, and 2offered on it the burnt offering and the meal offering, just as the Lord had commanded Moses. 30He placed the basin between the tent of meeting and the altar, and put water in it for washing. 313From it Moses and Aaron and his sons washed their hands and their feet. 32When they entered the tent of meeting, and when they approached the altar, they washed, just as the Lord had commanded Moses. 33And he 4erected the courtyard all around the 5tabernacle and the altar, and 6hung up the curtain for the gate of the courtyard. So Moses finished the work.
