Exodus 40:9-15

9“Then you shall take the anointing oil and anoint the tabernacle and all that is in it, and consecrate it and all its furniture, so that it may become holy. 10You shall also anoint the altar of burnt offering and all its utensils, and consecrate the altar, so that the altar may become most holy. 11You shall also anoint the basin and its stand, and consecrate it. 12Then you shall bring Aaron and his sons to the entrance of the tent of meeting and shall wash them with water 13and put on Aaron the holy garments. And you shall anoint him and consecrate him, that he may serve me as priest. 14You shall bring his sons also and put coats on them, 15and anoint them, as you anointed their father, that they may serve me as priests. And their anointing shall admit them to a perpetual priesthood throughout their generations.”
