as self-evident, according to Lev 6:15, that as every fresh generation entered upon office, the anointing would be repeated or renewed.
The sacrificial ceremony with which the consecration was concluded, consisted of a threefold sacrifice, the materials for which were not supplied by the persons about to be installed, but were no doubt provided by Moses at the expense of the congregation, for which the priesthood was instituted. Moses officiated as the mediator of the covenant, through whose service Aaron and his sons were to be consecrated as priests of Jehovah, and performed every part of the sacrificial rite-the slaughtering, sprinkling of the blood, and burning of the altar gifts, - just as the priests afterwards did at the public daily and festal sacrifices, the persons to be consecrated simply laying their hands upon the sacrificial animals, to set them apart as their representatives.

The first sacrifice was a sin-offering, for which a young ox was taken (Exo 29:1), as in the case of the sin-offerings for the high priest and the whole congregation (Lev 4:3, Lev 4:14): the highest kind of sacrificial animal, which corresponded to the position to be occupied by the priests in the Israelitish kingdom of God, as the ἐκλογή of the covenant nation. Moses put some of the blood with his finger upon the horns of the altar of burnt-offering, and poured the rest at the foot of the altar. The far portions (see Lev 3:3-4) he burned upon the altar; but the flesh of the ox, as well as the hide and dung, he burned outside the camp. According to the general rule of the sin-offerings, whose flesh was burnt outside the camp, the blood was brought into the sanctuary itself (Lev 6:23); but here it was only put upon the altar of burnt-offering to make this sin-offering a consecration-sacrifice. Moses was to take the blood to “purify (יחטּא) and sanctify the altar, to expiate it.” As the altar had been sanctified immediately before by the anointing with holy oil (Lev 8:11), the object of the cleansing or sanctification of it through the blood of the sacrifice cannot have been to purify it a second time from uncleanness, that still adhered to it, or was inherent in it; but just as the purification or expiation of the vessels or worship generally applied only to the sins of the nation, by which these vessels had been defiled (Lev 16:16, Lev 16:19), so here the purification of the altar with the blood of the sin-offering, upon which the priests had laid their hands,
