The covenant of priesthood must be made by sacrifice, as well as other
covenants, Ps. l. 5. And thus Christ was consecrated by the sacrifice
of himself, once for all. Sacrifices of each kind must be offered for
the priests, that they might with the more tenderness and concern offer
the gifts and sacrifices of the people, with compassion on the
ignorant, and on those that were out of the way, not insulting over
those for whom sacrifices were offered, remembering that they
themselves had had sacrifices offered for them, being compassed with
infirmity. 1. A bullock, the largest sacrifice, was offered for a
sin-offering (v. 14), that hereby atonement might be made, and they
might not bring any of the guilt of the sins of their former state into
the new character they were now to put on. When Isaiah was sent to be a
prophet, he was told to his comfort, Thy iniquity is taken away, Isa.
vi. 7. Ministers, that are to declare the remission of sins to others,
should give diligence to get it made sure to themselves in the first
place that their own sins are pardoned. Those to whom is committed the
ministry of reconciliation must first be reconciled to God themselves,
that they may deal for the souls of others as for their own. 2. A ram
was offered for a burnt-offering, v. 18-21. By this they gave to God
the glory of this great honour which was now put upon them, and
returned him praise for it, as Paul thanked Christ Jesus for putting
him into the ministry, 1 Tim. i. 12. They also signified the devoting
of themselves and all their services to the honour of God. 3. Another
ram, called the ram of consecration, was offered for a peace-offering,
v. 22, &c. The blood of it was part put on the priests, on their ears,
thumbs, and toes, and part sprinkled upon the altar; and thus he did
(as it were) marry them to the altar, upon which they must all their
days give attendance. All the ceremonies about this offering, as those
before, were appointed by the express command of God; and, if we
compare this chapter with Exod. xxix, we shall find that the
performance of the solemnity exactly agrees with the precept there, and
in nothing varies. Here, therefore, as in the account we had of the
tabernacle and its vessels, it is again and again repeated, As the Lord
commanded Moses. And thus Christ, when he sanctified himself with his
own blood, had an eye to his Father's will in it. As the Father gave me
commandment so I do, John xiv. 31; x. 18; vi. 38.
