And thou shalt sanctify them, that they may be most holy,.... By anointing them, and so be set apart for sacred uses only; as by the grace of the Holy Spirit, the people of God, the vessels of mercy, are really sanctified, and made meet for the master's use; and therefore it is called the sanctification of the Spirit, which is true holiness, in opposition to typical or ceremonial holiness, here intended; and if this holy anointing oil made those things most holy that were anointed with it, how much more must the grace of the Spirit those who partake of it; and though it is at present imperfect, it will be perfected, and become complete holiness, without which no man can see the Lord:whatsoever toucheth them shall be holy; as is said of the most holy altar, See Gill on "Ex 29:37".
The Targum of Jonathan interprets it of persons that approach these holy places, and things so anointed and sanctified, paraphrasing the words thus;"whosoever cometh unto them of the priests shall be holy, but of the rest of the tribes shall be burnt with flaming fire before the Lord.'
