Exodus 40:29-33

29And he set the altar of burnt offering at the entrance of the tabernacle of the tent of meeting, and offered on it the burnt offering and the grain offering, as the Lord had commanded Moses.

30He set the basin between the tent of meeting and the altar, and put water in it for washing,

31with which Moses and Aaron and his sons washed their hands and their feet.

32When they went into the tent of meeting, and when they approached the altar, they washed, as the Lord commanded Moses.

33And he erected the court around the tabernacle and the altar, and set up the screen of the gate of the court. So Moses finished the work.
