(18) And he brought the ram.--After their sins had been expiated by the sin offering, Moses offered for the consecrated priests one of the two rams which he was ordered to take (see Leviticus 8:2) as a burnt offering. With the exception of performing the sacerdotal rites himself, the ritual here described is in accordance with rules laid down in Leviticus 1:3-9.

Verses 18-21. - There is no deviation on the present occasion from the ritual appointed for the burnt offering. After the sin offering, righteousness is symbolically imputed to Aaron; after the burnt offering, holiness; then follows the peace offering of the ram, which completes and sacrificially effects the consecration.

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 he brought the ram for the burnt offering,.... One of the two he was ordered to take, Leviticus 8:2.

and Aaron and his sons laid their hands on the head of the ram; as they had done before on the head of the bullock, see Leviticus 8:14 their right hands, as the Targum of Jonathan, and that at the same time; not first Aaron and then his sons, as a famous grammarian, Aben Ezra makes mention of, thought; but, as he himself says, they laid them on together.
