TSK · Leviticus 8:12

You are to take the anointing oil and pour it on his head and anoint him.

For the Priest“‘If the high priest sins so that the people are guilty, on account of the sin he has committed he must present a flawless young bull to the LORD for a sin offering.

Anointing Aaron, his Sons, and their Garments Then Moses took some of the anointing oil and some of the blood which was on the altar and sprinkled it on Aaron and his garments, and on his sons and his sons’ garments with him. So he consecrated Aaron, his garments, and his sons and his sons’ garments with him.

Rules for the High Priest“‘The high priest– who is greater than his brothers, on whose head the anointing oil is poured, who has been ordained to wear the priestly garments– must neither dishevel the hair of his head nor tear his garments.
