Exodus 30:18-21 ▼

18 “You are to make a bronze basin with a bronze stand for washing. Set it between the Tent of Meeting and the altar, and put water in it,

19 with which Aaron and his sons are to wash their hands and feet.

20 Whenever they enter the Tent of Meeting or approach the altar to minister by presenting an offering made by fire to the LORD, they must wash with water so that they will not die.

21 Thus they are to wash their hands and feet so that they will not die; this shall be a permanent statute for Aaron and his descendants for the generations to come.”
