(30) And of the blood which was upon the altar.--That is, some of the blood of the ram of consecration, which was probably kept in the bowl, and placed upon the altar for this purpose. Whether the anointing oil and the blood were sprinkled separately, or whether they were mixed together, cannot possibly be gathered either from this passage, or from Exodus 29:21, which gives the order. As the sacred garments were the badge of office, they received the same cleansing and sanctification as the priests themselves. Hence the remark of the apostle, "almost all things were by the law purged with blood" (Hebrews 9:22).

Verse 30. - The sprinkling with oil and blood completes the ceremony of anointing, and suffices of itself for the sons of Aaron, in addition to their virtual participation in the anointing of their father (verse 12). "In the mingling of the blood and oil for the anointing seems to be taught that not sacrifice for sin alone suffices; but that with this must be joined the unction of the Holy Spirit" (Gardiner).

8:14-36 In these types we see our great High Priest, even Christ Jesus, solemnly appointed, anointed, and invested with his sacred office, by his own blood, and the influences of his Holy Spirit. He sanctifies the ordinances of religion, to the benefit of his people and the honour of God the Father; who for his sake accepts our worship, though it is polluted with sin. We may also rejoice, that he is a merciful and faithful High Priest, full of compassion to the feeble-minded and tempest-tossed soul. All true Christians are consecrated to be spiritual priests. We should seriously ask ourselves, whether in our daily walk we study to maintain this character? and abound in spiritual sacrifices, acceptable to God through Christ? If so, still there is no cause for boasting. Let us not despise our fellow-sinners; but remembering what we have done, and how we are saved, let us seek and pray for their salvation.And Moses took of the anointing oil, and of the blood which was upon the altar,.... Which was sprinkled upon the altar round about, Leviticus 8:24 and these two seem to be mixed together, since it follows:

and sprinkled it upon Aaron, &c. See Gill on Exodus 29:21.
