10111. To sanctify them. That this signifies that they may be in truths from good from the Lord, is evident from the signification of “being sanctified,” as being to represent the Lord and the holy things which are from Him (see n. 9956, 9988); thus in a spiritual sense it denotes to be led by the Lord, because the Lord alone is holy, and everything holy proceeds from Him (n. 8806, 9229, 9479, 9688, 9818, 9820). From this it is evident that to receive truths through good from the Lord, thus faith through love from Him to Him, is to be “sanctified.” This does not mean that regarded in himself a man is on this account holy, but the Lord with him; for faith and love are the Lord with man, because they are continually from Him.

9956. And shalt sanctify them. That this signifies thus a representative of the Lord as to the Divine Human, is evident from the signification of “sanctifying,” as being to represent holiness itself, which is the Lord as to the Divine Human, for it is this alone which is holy, and from which is all holiness in the heavens and on earth. Everyone is able to know that the oil did not sanctify; but that it induced a representative of holiness. The case herein is this. The Lord Himself is above the heavens, for He is the Sun of the angelic heaven. The Divine which thence proceeds from Him in the heavens is what is called “holy.” The Divine of the Lord above the heavens could not be represented, because it is infinite; but only the Divine of the Lord in the heavens, for this is accommodated to the reception of the angels there, who are finite. In their perception this Divine is the Lord’s Divine Human, which alone is holy, and which was represented. From this it is evident what is signified by being “sanctified,” and why after the anointing it was said, as in Moses, “Thou shalt anoint the altar, and sanctify it” (Exodus 29:36); “thou shalt anoint the Tent of meeting, and all things therein, and shalt sanctify them” (Exodus 30:26-29); “thou shalt anoint Aaron and sanctify him” (Exodus 40:13); “Moses anointed Aaron and his garments, his sons and their garments, and sanctified them” (Leviticus 8:13, 30); besides other passages. (That the Lord alone is holy, and that everything holy is from Him, and that all sanctification represented Him, see n. 9229, 9680; also that the Lord in the heavens is “the sanctuary,” and therefore also heaven, n. 9479; and that the Holy Spirit is the Divine that proceeds from the Lord, n. 9818, 9820)
