Exodus 30:25-29 What does the holy oil represent?

 

²⁵ And thou shalt make it an oil of holy ointment, an ointment compound after the art of the apothecary: it shall be an holy anointing oil.
²⁶ And thou shalt anoint the tabernacle of the congregation therewith, and the ark of the testimony,
²⁷ And the table and all his vessels, and the candlestick and his vessels, and the altar of incense,
²⁸ And the altar of burnt offering with all his vessels, and the laver and his foot.
²⁹ And thou shalt sanctify them, that they may be most holy: whatsoever toucheth them shall be holy.
-Exodus 30:25-29 King James Version (KJV)

...[7] That "oil" signifies the good of love, can be seen especially from the anointings among the sons of Israel, or in their church, which were effected by oil; for by oil all things of the church were inaugurated, and when they had been inaugurated they were called holy, as the altar and its vessels, the tent of meeting and all things therein, likewise those who officiated in the priesthood and their garments, and also the prophets and afterwards the kings. Anyone can see that it is not oil itself that makes holy, but it is that which is signified by "oil," which is the good of love to the Lord from the Lord; this is signified by "oil;" consequently when persons or things were anointed, from that moment they became representative, for the oil induced a representation of the Lord and of the good of love from Him. For the good of love to the Lord from the Lord is the holy itself of heaven and the church, since through it everything Divine flows in; consequently the things of heaven and the church, which are called things spiritual, are so far holy as they are grounded in this holy... [12] (3) "That they anointed the altar and all its vessels, and the tent of meeting, and all things therein," is evident from Moses: Jehovah said to Moses, Thou shalt anoint the altar, and sanctify it (Exod. 29:36). In the same: Thou shalt make the oil of anointing of holiness, wherewith thou shalt anoint the tent of meeting, and the ark of the Testimony, and the table, and all the vessels thereof, and the lampstand and all the vessels thereof, and the altar of incense, and the altar of burnt-offering, and all the vessels thereof, and the lavers, and the base. Thus shalt thou sanctify them, that they may be holy of holies; whosoever shall touch them shall sanctify himself (Exod. 30:25-29; 40:9-11; Lev. 8:10-12; Num. 7:1). The altars and the tent of meeting, with all things therein, were anointed that they might represent the Divine and holy things of heaven and the church, consequently the holy things of worship; and these they could not have represented unless they had been inaugurated by something significative of the good of love, for it is through the good of love that the Divine enters, and through it is present; the same is true in worship, without the good of love the Divine neither enters nor is present...
