Leviticus 8:6

And Moses brought Aaron and his sons, and washed them with water.

And Moses brought Aaron and his sons,.... To the laver which was in the court of the tabernacle

and washed them with water; to show that they should be clean that bear the vessels of the Lord, and offer the sacrifices of the people; all that are in public office in the house of God ought to have both clean hands and a pure heart, to hold the mystery of the faith in a pure conscience, and to be of a pure and holy conversation; and indeed all that are made kings and priests to God, as all the saints are, they are washed from their sins in the blood of Jesus, Revelation 1:5.
