Commentaries:
Here the priests are consecrated to the service of God at the Tabernacle, empowering them to act in God's behalf for the people in making the sacrifices. In verse 10, Moses takes the anointing oil and anoints the Tabernacle and all that was in it and sanctifies them. He sprinkles some of the oil on the altar seven times, anointing the altar and all of its utensils, as well as the laver and its base to sanctify them. He pours some of the anointing oil on Aaron's head, anointing him and setting him apart.
Remember the anointing oil is a type of the Holy Spirit of God. We find the Holy Spirit, as it were, being given to Aaron for the purpose of carrying out his spiritual responsibilities as high priest between God and the people. Thus, he is empowered and set apart—sanctified—to do this job.
