Ezekiel 44:16

They shall enter, the high priest and the other priests shall have right and liberty of entering, into my sanctuary; both to the altar, to the temple, and the high priest into the holy of holies. To my table; to set the shew-bread on, and to take it off. To minister unto me; to offer sacrifice at the altar, and incense in the house; this the priests did in their course; and of this line the high priest alone, once a year, in the day of expiation, went in to minister to the Lord in the holy of holies. They shall keep my charge: see Ezekiel 44:8.
