Exodus 30:18-21

Thomson(i) 18 Make a laver of brass with its base of brass for the purpose of washing. And thou shalt place it between the tabernacle of the testimony and the altar, and thou shalt pour water into it. 19 And out of it Aaron and his sons shall wash their hands and their feet with water. 20 When they go into the tabernacle of the testimony, they shall wash with water. That they may escape death, when they go to the altar to minister as priests and to carry up the whole burnt offerings to the Lord 21 they shall wash their hands and their feet with water; and when they go into the tabernacle of the testimony they shall wash with water that they may not die: and this shall be to them a perpetual ordinance; to him and his posterity after him.
