Exodus 40:9-16

“Take the anointing oil and anoint the Tabernacle and all its furnishings to consecrate them and make them holy. Anoint the altar of burnt offering and its utensils to consecrate them. Then the altar will become absolutely holy. Next anoint the washbasin and its stand to consecrate them. “Present Aaron and his sons at the entrance of the Tabernacle, and wash them with water. Dress Aaron with the sacred garments and anoint him, consecrating him to serve me as a priest. Then present his sons and dress them in their tunics. Anoint them as you did their father, so they may also serve me as priests. With their anointing, Aaron’s descendants are set apart for the priesthood forever, from generation to generation.” Moses proceeded to do everything just as the LORD had commanded him.
