The Altar of Incense
18“You shall also make a basin of bronze, with its base of bronze, for washing; and you shall put it between the tent of meeting and the altar, and you shall put water in it. 19Aaron and his sons shall wash their hands and their feet from it; 20when they enter the tent of meeting, they shall wash with water, so that they do not die; or when they approach the altar to minister, by offering up in smoke a fire sacrifice to the Lord. 21So they shall wash their hands and their feet, so that they do not die; and it shall be a permanent statute for them, for Aaron and his descendants throughout their generations.”
