Exodus 40:29-33

29He placed the altar of burnt offering near the entrance to the tabernacle, the Tent of Meeting, and offered on it the burnt offering and the grain offering, just as the LORD had commanded him.

30He placed the basin between the Tent of Meeting and the altar and put water in it for washing; 31and from it Moses, Aaron, and his sons washed their hands and feet. 32They washed whenever they entered the Tent of Meeting or approached the altar, just as the LORD had commanded Moses.

33And Moses set up the courtyard around the tabernacle and the altar, and he hung the curtain for the entrance to the courtyard. So Moses finished the work.
