Leviticus 8:6–7; Exodus 30:20

And Moses brought Aaron and his sons and washed them with water. And he put athe coat on him and tied the sash around his waist and clothed him with the robe and put the ephod on him and tied the skillfully woven band of the ephod around him, binding it to him with the band.1

20 When they go into the tent of meeting, or when they come near the altar to minister, to burn a food offering1 to the Lord, they shall wash with water, so that they may not die.
