Exodus 30:18-21

EJ2000(i) 18 Thou shalt also make a laver of brass, and its base also of brass, to wash with; and thou shalt place it between the tabernacle of the testimony and the altar, and thou shalt put water in it. 19 And from it Aaron and his sons shall wash their hands and their feet. 20 When they go into the tabernacle of the testimony, they shall wash with water that they not die, or when they come near to the altar to minister, to burn the offering unto the LORD that must be consumed by fire, 21 they shall wash their hands and their feet, that they not die. And he and his seed shall have it as a perpetual statute throughout their generations.
