Leviticus 8:10

"And Moses took the anointing oil, and anointed the tabernacle and all that was therein, and sanctified them. And he sprinkled thereof upon the altar seven times, and anointed the altar and its vessels, and the laver and its base, to sanctify them. And he poured of the anointing oil upon Aaron's head, and anointed him, to sanctify him. And Moses brought Aaron's sons, and clothed them with coats, and girded them with girdles, and bound head-tires upon them; as Jehovah commanded Moses."

"Poured of the anointing oil upon Aaron's head ..." There was a significant difference in the manner of anointing the High Priest and that of anointing the lesser priests, a difference required by the typical difference. Aaron represented Jesus Christ, the Great High Priest, and the lesser priests were typical of Christians. In both cases the anointing with the sacred oil, prepared after the prescription by God Himself, typified the reception of the Holy Spirit, not on the part of any of those priests, however, for the Holy Spirit would not come until after Jesus' Ascension into heaven. The lesser priests did not have the oil "poured" upon them, but merely "sprinkled" upon them. The Jewish interpretation of Leviticus 8:30, below, is that, "It constituted the anointing of the priests, while the High Priest was distinguished by having oil poured on his head (Leviticus 8:12)."[15] This difference was designed to show that Jesus received the Holy Spirit "without measure," that is, in its completeness and entirety, whereas, Christians receive merely a token, or "earnest" of the Holy Spirit (John 3:34; Ephesians 1:13,14). The amazing typology in these verses is simply astounding.

The clothing of the priests here shows that a double consecration was being made, that of the High Priest, and that of the priests ordinary. The marked difference in the High Priestly robes, and those of the other priests has already been made apparent in Exodus 28 and Exodus 29.
