Exodus 30:18–21

18*“Make a bronze basin with a bronze base. Place it between the Tent and the altar, and put water in it. 19Aaron and his sons are to use the water to wash their hands and feet 20before they go into the Tent or approach the altar to offer the food offering. Then they will not be killed. 21They must wash their hands and feet, so that they will not die. This is a rule which they and their descendants are to observe for ever.”
