Exodus 40:29-33

29Then he set the altar of burnt offering at the entrance of the Tabernacle, the Tent of Meeting, and offered upon it the burnt offering and the grain offering, just as Adonai had commanded Moses.

30Next he set up the basin between the Tent of Meeting and the altar and put water in it for washing,

31so that Moses, Aaron and his sons could wash their hands and their feet there.

32When they went into the Tent of Meeting and when they came near to the altar, they washed, just as Adonai had commanded Moses.

33He set up the courtyard around the Tabernacle and the altar and set up the screen at the gate of the courtyard. So Moses finished the work.
