Hebrews 8:3 Meaning and Commentary

Hebrews 8:3

For every high priest is ordained to offer gifts and
sacrifices (See Gill on Hebrews 5:1)

wherefore it is of necessity that this man have somewhat also to offer;
or this person; for the word "man" is not in the text, and seems not so proper a word to be supplied, since it was his human nature that it was necessary he should have to offer; he was a person, and existed as a divine person antecedent to his assumption of human nature: as God, he had nothing to offer, or that was capable of being offered; something to offer as a sacrifice was necessary to him as a priest, but not any thing was proper to him; Levitical sacrifices would not do, these could not take away sin; besides, the great high priest was not of the tribe of Levi, nor of the order of Aaron, and therefore could not offer these. An angelic nature would have been improper, that is not capable of dying; and the offering up of such an one would have been of no service to men, for whom priests are ordained; but an human nature is meant, and which it was necessary Christ should have, and offer, for it is for men that he became an high priest; it was human nature that had offended God, and satisfaction must be made in that nature; and this was capable of suffering and dying; yet not human nature under any consideration was necessary for him to have and offer; not merely as in a state of innocence, without any infirmity, nor as sinful, yet as perfect as to parts and qualities; and a nature, and not a person, was necessary to be had, and to be taken into close and inseparable union to his divine person; and of this there was a necessity, not absolute, or a necessity of coaction and force: Christ was not forced unto it; but on the foot of his suretyship engagements, and because of making satisfaction for the sin of man, it was necessary; otherwise Christ voluntarily engaged to be a priest, and willingly became man, and freely offered himself, soul and body, in the room and stead of his people.

Hebrews 8:3 In-Context

1 And the sum concerning the things spoken of [is]: we have such a chief priest, who did sit down at the right hand of the throne of the greatness in the heavens,
2 of the holy places a servant, and of the true tabernacle, which the Lord did set up, and not man,
3 for every chief priest to offer both gifts and sacrifices is appointed, whence [it is] necessary for this one to have also something that he may offer;
4 for if, indeed, he were upon earth, he would not be a priest -- (there being the priests who are offering according to the law, the gifts,
5 who unto an example and shadow do serve of the heavenly things, as Moses hath been divinely warned, being about to construct the tabernacle, for `See (saith He) thou mayest make all things according to the pattern that was shewn to thee in the mount;') --
