Thou shalt anoint Aaron and his sons - For the reason of this anointing, see Clarke's note on Exodus 29:7. It seems that this anointing oil was an emblem of Divine teaching, and especially of those influences by which the Church of Christ was, in the beginning, guided into all truth; as is evident from the allusion to it by St. John: "Ye have an unction from the Holy One, and ye know all things. The anointing which ye have received from him abideth in you, and ye need not that any man teach you; but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in Him; 1-John 2:20, 1-John 2:27.
And thou shall anoint Aaron and his sons,.... Them alone, and not others, as Aben Ezra, who were typical of Christ anointed with the Spirit of God without measure, to his various offices of prophet, priest and King; and also of all the saints, who are anointed priests to God, to offer up spiritual sacrifices acceptable to God through Christ:
and consecrate them, that they may minister unto me in the priest's office; by anointing them, and by other rites mentioned in the preceding chapter; whereby they were set apart for that office, and were qualified for it, and had authority to exercise it.
