TSK · Exodus 29:21

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

“You are to anoint Aaron and his sons and sanctify them, so that they may minister as my priests.

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.

and the remainder of the olive oil that is in the hand of the priest he is to put on the head of the one being cleansed to make atonement for him before the LORD.

The LORD’s Spirit will rest on him– a Spirit that gives extraordinary wisdom, a Spirit that provides the ability to execute plans, a Spirit that produces absolute loyalty to the LORD.

And I set myself apart on their behalf, so that they too may be truly set apart.

How much greater punishment do you think that person deserves who has contempt for the Son of God, and profanes the blood of the covenant that made him holy, and insults the Spirit of grace?
