(44) I will sanctify also both Aaron and his sons.--Something beyond the formal consecration seems to be intended. God will continually sanctify the Levitical priesthood by the presence of His Holy Spirit with them, in their ministerial acts, and even in their daily walk, if they will seek to serve Him.

Verse 44. - I will sanctify... the altar. See Leviticus 9:24, where we learn that on the first occasion of Aaron's offering sacrifice upon the brazen altar, "there came a fire out from before the Lord, and consumed upon the altar the burnt offering and the fat." Thus the altar had its miraculous sanctification, as well as the tabernacle, and was not merely consecrated by human instrumentality. I will sanctify also both Aaron and his sons. It would seem to follow, by parity of reasoning, that here also something more is intended than had been accomplished by the rites of consecration. The verb is in the future - "I will sanctify" - and must allude to something which has not yet taken place. Probably, sanctification of the spirit is intended - that Divine influence upon the heart which alone makes men really and truly "holy." (Compare Leviticus 21:8, 15; Leviticus 22:9, 16.) But in this case the promise must have been conditional. God would sanctify them so far as they would allow him.

29:38-46 A lamb was to be offered upon the altar every morning, and a lamb every evening. This typified the continual intercession which Christ ever lives to make for his church. Though he offered himself but once for all, that one offering thus becomes a continual offering. This also teaches us to offer to God the spiritual sacrifices of prayer and praise every day, morning and evening. Our daily devotions are the most needful of our daily works, and the most pleasant of our daily comforts. Prayer-time must be kept up as duly as meal-time. Those starve their own souls, who keep not up constant attendance on the throne of grace; constancy in religion brings in the comfort of it.And I will sanctify the tabernacle of the congregation, and the altar,.... This seems to intimate that something else in the preceding verse is intended, as what should be sanctified, than the tabernacle, as we supply it; or else here is a repetition of the same thing for the confirmation of it, and both that and the altar were, sanctified, or set apart for holy uses, as well as cleansed and expiated by sacrifices:

I will sanctify also both Aaron and his sons, to minister to me in the priest's office; that is, in a ceremonial way, by separating them from the rest of the children of Israel, by washing, clothing, and anointing them, and by accepting sacrifices offered by them; for this is not to be understood of internal sanctifying grace, which, though Aaron had, and many of his sons that succeeded him, yet not all; nor was it necessary to the performance of the priestly office, though it is in all those who are a royal priesthood, and made priests as well as kings unto God; for they are a holy nation, called with an holy calling, and unto himself, and have it both internally and externally.
