2. [Second part of the high priest's office]. This was one part of his office; when this was done, he was in the next place (1.) To put on the glorious garment, when he was to go into the holiest, take off sacred the blood, carry it thither, etc., he was to put on the holy garment which signified the righteousness of Jesus Christ. (2.) He was in this sacred garment, which hath in it the stones, and in the names of the twelve tribes of the children of Israel, to appear in the holy place. "And thou shalt take two onyx stones, and grave on them the names of the children of Israel: six of their names on one stone, and the other six names of the rest on the other stone, according to their birth" (Exo 28:9,10). This was to signify that Jesus Christ was to enter into the holiest, and then He was there to bear the names of His elect in the tables of His heart before the Throne of God and the Mercy-seat (Heb 12:23). (3.) With this mercy seat, he was to take of the blood of the sacrifices and carry it into the holiest of all, which was a type of Heaven, and there was he to sprinkle the mercy-seat; and this was to be done by the high priest only; to signify, that none but Jesus Christ must have this office and privilege, to be the people's High Priest to offer for them. "But into the second went the high priest alone once every year, not without blood, which he offered for himself, and for the errors of the people" (Heb 9:7). (4.) He was there to make an atonement for the people with the blood, sprinkling of it upon the mercy-seat; but this must be done with much incense. "And Aaron shall bring the bullock of the sin-offering which is for himself, and for his house, and shall kill the bullock of the sin-offering which is for himself: and he shall take a censor full of burning coals of fire from off the altar before the Lord, and his hands full of sweet incense beaten small, and bring it within the veil: and he shall put the incense upon the fire before the Lord, that he cloud of the incense may cover the mercy-seat that is upon the testimony, that he die not: and he shall take of the blood of the bullock, and sprinkle it with his finger upon the mercy-seat eastward, and before the mercy-seat shall he sprinkle of the blood with his finger seven times. Then shall he kill the goat of the sin-offering, that is for the people, and bring his blood within the veil, and do with that blood as he did with the blood of the bullock, and sprinkle it upon the mercy-seat and before the mercy-seat." (Lev 16:11-15). Now this was for the priest and the people; all which doth signify that Jesus Christ was after His death to go into Heaven itself, of which this holy place was a figure, and there to carry the sacrifice that He offered upon the Cross into the presence of God, to obtain mercy for the people in a way of justice (Heb 9). And in that he is said to take his hands full of sweet incense, it signifies that Jesus Christ was to offer up His sacrifice in the presence of His Father in a way of intercession and prayers.
I might have branched these things into several particulars, but I would be brief. I say, therefore, the priest's office was to carry the blood into the holy place and present it before the mercy seat, with his heart whole of intercessions for the people for whom he was a priest (Luke 1:8-11). This is Jesus Christ's work now in the Kingdom of Glory, to plead His own blood, the nature and virtue of it, with a perpetual intercession to the God of Mercy on behalf of us poor miserable sinners (Heb 7:25).
