Exodus 40:31-33 New Living Translation (NLT)

31. Moses and Aaron and Aaron’s sons used water from it to wash their hands and feet.

32. Whenever they approached the altar and entered the Tabernacle, they washed themselves, just as the lord had commanded Moses.

33. Then he hung the curtains forming the courtyard around the Tabernacle and the altar. And he set up the curtain at the entrance of the courtyard. So at last Moses finished the work.
