It is Most Holy

In these two chapters, the priests stand before us pre-eminently as types and pictures of our Lord Jesus Christ, our great High Priest before God; and the entire work they performed under the law of God in offering these daily sacrifices is declared to be “most holy.” — “It is most holy.”

"It is most holy." - Those words apply not to the sacrifice alone, but to the offering of the sacrifice, the burning of the sacrifice, the eating of the sacrifice, the place of the sacrifice, and the priests who offered the sacrifice. They are specifically applied to the ceremonies relating to the meat offering, the sin offering, and the trespass offering.
