(15) Thou shalt anoint them, as thou didst anoint their father.--By the narrative of Leviticus 8, it would seem that Aaron's sons were not anointed in the same way as himself. He had the oil poured over his head (Leviticus 8:12; Psalm 133:2). They were merely sprinkled with a mixture of oil and blood (Leviticus 8:30). The difference implied a lower degree of official holiness.

Their anointing shall surely be an everlasting priesthood.--The Jewish commentators maintain that the one anointing of the sons of Aaron sufficed for all time, and was not repeated in the case of any subsequent priests, who became fully possessed of the sacerdotal office without it. Each high priest was, on the contrary, inducted into his office by anointing, whence the high priest came to be spoken of as "the anointed priest (Leviticus 4:3; Leviticus 4:5; Leviticus 4:16; Leviticus 21:12, &c.).

Verse 15. - Thou shalt anoint them as thou didst anoint their father. The mode of anointing does not seem to have been identical in the two cases. The oil was first poured upon Aaron's head (Leviticus 8:12; Psalm 133:2), and afterwards sprinkled upon him (Leviticus 8:30). It was, apparently, only sprinkled upon the priests (ib,). This was a lower form of anointing; and hence the high priest was sometimes called "the anointed priest" (Leviticus 4:5, 16; Leviticus 6:22; Leviticus 16:32, etc.). Their anointing shall surely be an everlasting priesthood. The Rabbinical commentators maintain that these words apply to the ordinary priests only, and on the strength of them establish a difference between the ordinary priests and the high priests. The latter were in every ease to be anointed to their office. A single anointing sainted for the former. It is scarcely necessary to say that there is no Scriptural ground for this distinction. The natural sense of the words is, rather, that as long as the anointing continued, the priesthood should continue.

40:1-15 When a new year begins, we should seek to serve God better than the year before. In half a year the tabernacle was completed. When the hearts of numbers are earnest in a good cause, much may be done in a short time; and when the commandments of God are continually attended to, as the rule of working, all will be done well. The high-priesthood was in the family of Aaron till Christ came, and in Him, the substance of all these shadows, it continues for ever.And thou shall anoint them as thou didst anoint their father,.... For Aaron was first anointed, and then his sons:

that they may minister unto me in the priest's office; which they might not do before their anointing, though separated for it, and called unto it:

for their anointing shall surely be an everlasting priesthood throughout their generations; that is, this ceremony of anointing was to be used in all ages at the investiture of the high priest with his office, until the Messiah should come, who would put an end to the Aaronic priesthood; for not common priests, only the successors of the high priest, were anointed in later times; this present unction serving for all the priests that should follow in successive generations, so long as the priesthood continued.
