No ministration was to be performed even by the inferior priests of the four sons of Aaron, without being clad in their vestments. Was not this intended to show, that in all the approaches of the Lord's people before God, they must be clothed in the robes of Jesus' s righteousness? In ourselves we are polluted, and without Jesus we bear our own iniquity and must die. The man in the parable without the wedding garment is a type of this. Matthew 22:11-13; Isaiah 61:10.
