(3) This verse and the three following confirm and illustrate the importance of the statement just made. The general course of thought appears to be as follows:--That which stands "at the head" of what we are saying, and gives completeness to the whole, is, that we have a High Priest who ministers in heaven itself (Hebrews 8:1-2). For, whereas the very conception of high-priestly duty would, were He on earth, exclude Him from being a priest at all (Hebrews 8:3-4), like those who "serve a copy of the heavenly things" (Hebrews 8:5), He in heaven holds and exercises that more excellent ministry of which their service was a shadow and a type (Hebrews 8:6).

That this man have . . .--Better, that this High Priest also have somewhat to offer. If these words refer to the continued ministration in the heavenly sanctuary, the explanation is found in Hebrews 9:24; but the meaning may simply be that every high priest, and therefore the Lord Jesus, must have some sacrifice to present to God, this being (Hebrews 5:1) the very object of his appointment to the office.

Verses 3, 4. - For every high priest is appointed to offer gifts and sacrifices: wherefore it is of necessity that this one also have somewhat to offer. For (rather, nay; the reading μὲν οῦν being better supported than the Textus Receptus μὲν γὰρ) if he were on earth, he would not even be a priest, seeing there are those who offer the gifts according to the Law. These verses are in proof of the assertion of ver. 2, viz. that Christ has his ministry in the heavenly tabernacle. He has been shown to be a High Priest: therefore he must make some offering, this being the very purpose of a high priest's office (cf. Hebrews 5:1). But where? Not certainly in the earthly tabernacle, this being served already, and exclusively served, by the sons of Aaron. Therefore it must be in the heavenly sphere symbolized by the earthly tabernacle. And then, in ver. 5, that there is a heavenly reality, of which the earthly tabernacle is but a shadow, is shown by what was said of the latter when it was made. (What Christ offers in the heavenly sphere is surely his own atoning sacrifice. Some commentators have found a difficulty in this conception on the ground that this his sacrifice had been completed once for all before his ascension. True; but he is regarded as carrying its efficacy with him to the mercy-seat above, and so for ever offering it; even as it is continually commemorated and pleaded in the Eucharist by the Church below. And thus, be it observed, the symbolism of the Day of Atonement is accurately fulfilled. For the high priest did not sacrifice within the tabernacle; he only carried to the holy of holies the blood, representing the atoning efficacy of the sacrifice made outside before his entrance.)

8:1-6 The substance, or summary, of what had been declared was, that Christians had such a High Priest as they needed. He took upon himself human nature, appeared on earth, and there gave himself as a sacrifice to God for the sins of his people. We must not dare to approach God, or to present any thing to him, but in and through Christ, depending upon his merits and mediation; for we are accepted only in the Beloved. In all obedience and worship, we should keep close to God's word, which is the only and perfect standard. Christ is the substance and end of the law of righteousness. But the covenant here referred to, was that made with Israel as a nation, securing temporal benefits to them. The promises of all spiritual blessings, and of eternal life, revealed in the gospel, and made sure through Christ, are of infinitely greater value. Let us bless God that we have a High Priest that suits our helpless condition.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.
