14 And he brought the bullock for the sin offering: and Aaron and his sons laid their hands upon the head of the bullock for the sin offering.   15 And he slew it; and Moses took the blood, and put it upon the horns of the altar round about with his finger, and purified the altar, and poured the blood at the bottom of the altar, and sanctified it, to make reconciliation upon it.   16 And he took all the fat that was upon the inwards, and the caul above the liver, and the two kidneys, and their fat, and Moses burned it upon the altar.   17 But the bullock, and his hide, his flesh, and his dung, he burnt with fire without the camp; as the LORD commanded Moses.   18 And he brought the ram for the burnt offering: and Aaron and his sons laid their hands upon the head of the ram.   19 And he killed it; and Moses sprinkled the blood upon the altar round about.   20 And he cut the ram into pieces; and Moses burnt the head, and the pieces, and the fat.   21 And he washed the inwards and the legs in water; and Moses burnt the whole ram upon the altar: it was a burnt sacrifice for a sweet savour, and an offering made by fire unto the LORD; as the LORD commanded Moses.   22 And he brought the other ram, the ram of consecration: and Aaron and his sons laid their hands upon the head of the ram.   23 And he slew it; and Moses took of the blood of it, and put it upon the tip of Aaron's right ear, and upon the thumb of his right hand, and upon the great toe of his right foot.   24 And he brought Aaron's sons, and Moses put of the blood upon the tip of their right ear, and upon the thumbs of their right hands, and upon the great toes of their right feet: and Moses sprinkled the blood upon the altar round about.   25 And he took the fat, and the rump, and all the fat that was upon the inwards, and the caul above the liver, and the two kidneys, and their fat, and the right shoulder:   26 And out of the basket of unleavened bread, that was before the LORD, he took one unleavened cake, and a cake of oiled bread, and one wafer, and put them on the fat, and upon the right shoulder:   27 And he put all upon Aaron's hands, and upon his sons' hands, and waved them for a wave offering before the LORD.   28 And Moses took them from off their hands, and burnt them on the altar upon the burnt offering: they were consecrations for a sweet savour: it is an offering made by fire unto the LORD.   29 And Moses took the breast, and waved it for a wave offering before the LORD: for of the ram of consecration it was Moses' part; as the LORD commanded Moses.   30 And Moses took of the anointing oil, and of the blood which was upon the altar, and sprinkled it upon Aaron, and upon his garments, and upon his sons, and upon his sons' garments with him; and sanctified Aaron, and his garments, and his sons, and his sons' garments with him.

      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.
