Exodus 40:13

Verse 13. Priesthood. Hebrew “And thou shalt put upon Aaron the holy garments, and anoint him, and sanctify him, that he may serve me in the priest’s office: (14) and thou shalt bring his sons, and put on them their tunics; (15) and thou shalt anoint them, as thou didst anoint their father, that they may perform the office of priests to me for ever, in their generations.” As the priesthood was hereditary in Aaron’s family, this first unction might suffice for all. Yet, the new high priests were always anointed till the days of our Saviour. Calmet. 29:7.
