(12) And he poured of the anointing oil upon Aaron's head.--In the anointing of Aaron, the oil was poured upon his head. (See also Leviticus 21:10-12; Exodus 29:7; Psalm 133:2.) This profuse pouring of oil was repeated at the consecration of every successor to the high-priesthood, whilst the common priests were simply anointed, or were simply marked with the finger on the forehead on their first installation, and this anointing descended with them for all futurity. (See Leviticus 6:3.) Tradition informs us that during the second Temple, the person who anointed the high priest first threw the oil upon his head, and then drew with his finger the sign of the letter Caph, being the initial of Cohen, i.e., priest, between the eyebrows of the newly-consecrated pontiff.

Verse 12. - He poured of the anointing oil upon Aaron's head. The change of the verb poured for sprinkled, indicates that the amount of "the precious ointment" poured "upon the head, that ran down unto the beard, and went down to the skirts of his garments" (Psalm 133:2), was far greater than that with which the furniture of the tabernacle had been anointed. The oil sprinkled on the holy things sanctified them as means of grace. The oil poured upon Aaron represents the grace of the Holy Spirit, coming from without, but diffusing itself over and throughout the whole consecrated man.

8:1-13 The consecration of Aaron and his sons had been delayed until the tabernacle had been prepared, and the laws of the sacrifices given. Aaron and his sons were washed with water, to signify that they ought to purify themselves from all sinful dispositions, and ever after to keep themselves pure. Christ washes those from their sins in his own blood whom he makes kings and priests to our God, Re 1:5,6; and those that draw near to God must be washed in pure water, Heb 10:22. The anointing of Aaron was to typify the anointing of Christ with the Spirit, which was not given by measure to him. All believers have received the anointing.And he poured of the anointing oil upon Aaron's head,.... Which ran down to his beard, and to the collar of his coat, the robe of the ephod, but not to the skirts of his garments, as we wrongly render it, Psalm 133:2. Jarchi says it was first poured on his head, and after that he put it between his eyebrows, and drew it with his finger here and there, or from one eyebrow to another: Maimonides (w) gives a like account, with some addition; he says, the oil was poured on his head, and he was anointed between the eyebrows, in the form of the Greek letter "chi": a greater profusion of oil was used in the anointing of Aaron than of the tabernacle, altar, and laver, and their vessels, he being so eminent a type of Christ, our high priest, anointed with the oil of gladness above his fellows:

and anointed him to sanctify him; to signify that he was set apart and devoted to the sacred office of the priesthood. The Targum of Jonathan observes, that this anointing was after he had clothed him; though some have thought it was done before the mitre and holy crown were put on: but if they were put on to complete the investiture, they might be taken off while the ceremony of anointing was performed.
