Exodus 29:6-9

Place the turban on his head, and fasten the sacred medallion to the turban. Then anoint him by pouring the anointing oil over his head. Next present his sons, and dress them in their tunics. Wrap the sashes around the waists of Aaron and his sons, and put their special head coverings on them. Then the right to the priesthood will be theirs by law forever. In this way, you will ordain Aaron and his sons.
