Exodus 30:17-21 - The Bronze Basin
18 And thou shalt make a laver of bronze, and its stand of bronze for bathing, - and thou shalt place it between the tent of meeting and the altar, and shalt put therein water. 19 So shall Aaron and his sons bathe thereat, - their hands, and their feet. 20 When they enter the tent of meeting, they shall bathe with water so shall they not die, - or when they approach unto the altar to minister, to burn as incense an altar-flame to Yahweh: 21 so then they shall bathe their hands and their feet and shall not die, - and it shall be to them an age-abiding statute, to him and to his seed to their generations.
