SEV Biblia, Chapter 40:15
Y los ungirás como ungiste a su padre, y serán mis sacerdotes; y será que su unción les será por sacerdocio perpetuo por sus generaciones.
Clarke's Bible Commentary - Exodus 40:15
Verse 15. 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 honour 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 Lev. iv. 3; vi. 22; xxi. 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 on chap. xxxix. 7. See the note on "chap. xxix. 7". The Jewish high priest was a type of Him who is called the high priest over the house of God, Heb. x. 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.
Matthew Henry Commentary
Verses 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 short time; and when the commandments of God are continually attende to, as the rule of working, all will be done well. The high-priesthoo was in the family of Aaron till Christ came, and in Him, the substanc of all these shadows, it continues for ever.
