For their anointing shall surely be an everlasting priesthood - By this anointing a right was given to Aaron and his family to be high priests among the Jews for ever; so that all who should be born of this family should have a right to the priesthood without the repetition of this unction, as they should enjoy this honor in their father's right, who had it by a particular grant from God. But it appears that the high priest, on his consecration, did receive the holy unction; see Leviticus 4:3; Leviticus 6:22; Leviticus 21:10. And this continued till the destruction of the first temple, and the Babylonish captivity; and according to Eusebius, Cyril of Jerusalem, and others, this custom continued among the Jews to the advent of our Lord, after which there is no evidence it was ever practiced. See Calmet's note Exodus 29:7 (note). The Jewish high priest was a type of Him who is called the high priest over the house of God, Hebrews 10:21; and when he came, the functions of the other necessarily ceased. This case is worthy of observation. The Jewish sacrifices were never resumed after the destruction of their city and temple, for they hold it unlawful to sacrifice anywhere out of Jerusalem; and the unction of their high priest ceased from that period also: and why? Because the true priest and the true sacrifice were come, and the types of course were no longer necessary after the manifestation of the antitype.

Exodus
The book of Exodus--so named in the Greek version from the march of Israel out of Egypt--opens upon a scene of oppression very different from the prosperity and triumph in which Genesis had closed. Israel is being cruelly crushed by the new dynasty which has arisen in Egypt (i.) and the story of the book is the story of her redemption. Ultimately it is Israel's God that is her redeemer, but He operates largely by human means; and the first step is the preparation of a deliverer, Moses, whose parentage, …
