For verily, or, For nowhere, etc. By this comparison he enhances the benefit and the honor with which Christ has favored us, by putting on our flesh; for he never did so much for angels. As then it was necessary that there should be a remarkable remedy for man's dreadful ruin, it was the design of the Son of God that there should be some incomparable pledge of his love towards us which angels had not in common with us. That he preferred us to angels was not owing to our excellency, but to our misery. There is therefore no reason for us to glory as though we were superior to angels, except that our heavenly Father has manifested toward us that ampler mercy which we needed, so that the angels themselves might from on high behold so great a bounty poured on the earth. The present tense of the verb is to be understood with reference to the testimonies of Scripture, as though he set before us what had been before testified by the Prophets. But this one passage is abundantly sufficient to lay prostrate such men as Marcion and Manicheus, and fanatical men of similar character, who denied Christ to have been a real man, begotten of human seed. For if he bore only the appearance of man, as he had before appeared in the form of an angel, there could have been no difference; but as it could not have been said that Christ became really an angel, clothed with angelic nature, it is hence said that he took upon him man's nature and not that of angels. And the Apostle speaks of nature, and intimates that Christ, clothed with flesh, was real man, so that there was unity of person in two natures. For this passage does not favor Nestorius, who imagined a twofold Christ, as though the Son of God was not a real man but only dwelt in man's flesh. But we see that the Apostle's meaning was very different, for his object was to teach us that we find in the Son of God a brother, being a partaker of our common nature. Being not therefore satisfied with calling him man, he says that he was begotten of human seed; and he names expressly the seed of Abraham, in order that what he said might have more credit, as being taken from Scripture.

For verily - Truly.
He took not on him the nature of angels - Margin, "He taketh not hold of angels, but of the seed of Abraham he taketh hold." The word used here - ἐπιλαμβάνεται epilambanetai - means, to take hold upon; to seize; to surprise; to take hold with a view to detain for oneself. Robinson. Then it means to take hold of one as by the hand - with a view to aid, conduct, or succour; Mark 8:23; Acts 23:19. It is rendered "took," Mark 8:23; Luke 9:47; Luke 14:4; Acts 9:27; Acts 17:19; Acts 18:17; Acts 21:30, Acts 21:33; Acts 23:19; Hebrews 8:9; "caught," Matthew 14:31; Acts 16:19; "take hold," Luke 20:20, Luke 20:26; "lay hold," and "laid hold," Luke 23:26; 1-Timothy 6:12. The general idea is that of seizing upon, or laying hold of anyone - no matter what the object is - whether to aid, or to drag to punishment, or simply to conduct. Here it means to lay hold with reference to "aid," or "help;" and the meaning is, that he did not seize the nature of angels, or take it to himself with reference to rendering "them" aid, but he assumed the nature of man - in order to aid "him." He undertook the work of human redemption, and consequently it was necessary for him to be man.
But he took on him the seed of Abraham - He came to help the descendants of Abraham, and consequently, since they were men, he became a man. Writing to Jews, it was not unnatural for the apostle to refer particularly to them as the descendants of Abraham, though this does not exclude the idea that he died for the whole human race. It was true that he came to render aid to the descendants of Abraham, but it was also true that he died for all. The fact that I love one of my children, and that I make provision for his education, and tell him so, does not exclude the idea that I love the others also - and that I may make to them a similar appeal when it shall be proper.

For verily he took not on him the nature of angels - Ου γαρ δηπου αγγελων επιλαμβανεται, αλλα σπερματος Αβρααμ επιλαμβανεται· Moreover, he doth not at all take hold of angels; but of the seed of Abraham he taketh hold. This is the marginal reading, and is greatly to be preferred to that in the text Jesus Christ, intending not to redeem angels, but to redeem man, did not assume the angelic nature, but was made man, coming directly by the seed or posterity of Abraham, with whom the original covenant was made, that in his seed all the nations of the earth should be blessed; and it is on this account that the apostle mentioned the seed of Abraham, and not the seed of Adam; and it is strange that to many commentators should have missed so obvious a sense. The word itself signifies not only to take hold of, but to help, succor, save from sinking, etc. The rebel angels, who sinned and fell from God, were permitted to fall down, alle downe, as one of our old writers expresses it, till they fell into perdition: man sinned and fell, and was falling downe, alle downe, but Jesus laid hold on him and prevented him from falling into endless perdition. Thus he seized on the falling human creature, and prevented him from falling into the bottomless pit; but he did not seize on the falling angels, and they fell down into outer darkness. By assuming the nature of man, he prevented this final and irrecoverable fall of man; and by making an atonement in human nature, he made a provision for its restoration to its forfeited blessedness. This is a fine thought of the apostle, and is beautifully expressed. Man was falling from heaven, and Jesus caught hold of the falling creature, and prevented its endless ruin. In this respect he prefers men to angels, and probably for this simple reason, that the human nature was more excellent than the angelic; and it is suitable to the wisdom of the Divine Being to regard all the works of his hands in proportion to the dignity or excellence with which he has endowed them.

(15) For verily he took not on [him the (b) nature of] angels; but he took on [him] the (c) seed of Abraham.
(15) He explains those words of flesh and blood, showing that Christ is true man, and not by changing his divine nature, but by taking on man's nature. He names Abraham, regarding the promises made to Abraham in this behalf.
(b) The nature of angels.
(c) The very nature of man.

For verily he took not on him the nature of angels,.... Good angels; for they are all along spoken of in this book; and it would have been impertinent to have said this of evil angels: and this is to be understood not of a denying help and assistance to the angels; for though they have not redemption from Christ, which they needed not, yet have they help from him; they are chosen in him, and are gathered together under him; and he is the head of them, and they are upheld and sustained by him in their being, and well being: but of a non-assumption of their nature; there was no need of it with respect to good angels, and there was no salvation designed for evil ones; and to have assumed the nature of angels, would have been of no service to fallen man; an angelic nature is not capable of death, which was necessary to atone for sin, save men, and destroy Satan: this negative proposition is very strongly put, "he never took", as the Vulgate Latin version more rightly renders it; at no time, in no place; nor is it said in any place of Scripture that he did; this is a certain truth, and not to be disputed. The Syriac and Arabic versions render it, "he took not of, or from angels"; he took not any individual from among them:
but he took on him the seed of Abraham; not all his posterity, but some individual, as the word seed is sometimes used, Genesis 4:25. Christ assumed human nature as derived from Abraham; for the Messiah was to spring from Abraham, and is promised, as that seed of his, in whom all nations should be blessed; and he was particularly promised to the Jews, the seed of Abraham, to whom the apostle was writing; and it was with a view to Abraham's spiritual seed, the children of the promise, that Christ partook of flesh and blood: the word here used signifies to catch hold of anyone ready to perish, or to lay hold on a person running away, and with great vehemence and affection to hold anything fast, that it be not lost, and to help persons, and do good unto them; all which may be observed in this act of Christ's, in assuming an individual of human nature, in Abraham's line, into union with his divine person; whereby he has saved those that were gone out of the way, and were ready to perish, and done them the greatest good, and shown the strongest affection to them: and from hence may be learned the deity and eternity of Christ, who was before Abraham, as God, though a son of his as man; and his real humanity, and that it was not a person, but a seed, a nature he assumed; and also the union and distinction of natures in him: and Christ's taking human, and not angelic nature, shows the sovereignty of God, and his distinguishing grace and mercy to men.

For verily--Greek, "For as we all know"; "For as you will doubtless grant." Paul probably alludes to Isaiah 41:8; Jeremiah 31:32, Septuagint, from which all Jews would know well that the fact here stated as to Messiah was what the prophets had led them to expect.
took not on him, &c.--rather, "It is not angels that He is helping (the present tense implies duration); but it is the seed of Abraham that He is helping." The verb is literally, to help by taking one by the hand, as in Hebrews 8:9, "When I took them by the hand," &c. Thus it answers to "succor," Hebrews 2:18, and "deliver," Hebrews 2:15. "Not angels," who have no flesh and blood, but "the children," who have "flesh and blood," He takes hold of to help by "Himself taking part of the same" (Hebrews 2:14). Whatever effect Christ's work may have on angels, He is not taking hold to help them by suffering in their nature to deliver them from death, as in our case.
the seed of Abraham--He views Christ's redemption (in compliment to the Hebrews whom he is addressing, and as enough for his present purpose) with reference to Abraham's seed, the Jewish nation, primarily; not that he excludes the Gentiles (Hebrews 2:9, "for every man"), who, when believers, are the seed of Abraham spiritually (compare Hebrews 2:12; Psalm 22:22, Psalm 22:25, Psalm 22:27), but direct reference to them (such as is in Romans 4:11-12, Romans 4:16; Galatians 3:7, Galatians 3:14, Galatians 3:28-29) would be out of place in his present argument. It is the same argument for Jesus being the Christ which Matthew, writing his Gospel for the Hebrews, uses, tracing the genealogy of Jesus from Abraham, the father of the Jews, and the one to whom the promises were given, on which the Jews especially prided themselves (compare Romans 9:4-5).

He took not the nature. He did not lay hold of an angel form in order to save angels, but the human form and nature, in order to be our Savior. He chose to be the seed of Abraham, being the Son of Mary, a descendant of Abraham.
It behoved him to be made like his brethren. Hence, for the reasons given above, it was necessary that he take our nature.
A merciful and faithful high priest. To be our high priest he must be in full sympathy with us, having experienced our trials and our sufferings.
To make propitiation. As our high priest he made atonement for us. Conscious of all our frailties he intercedes for us. In him, the Divine man, all who are found in him are justified before God.
In that he suffered, he is able to sympathize with all who suffer and to succor all who have trials and need help.

For verily he taketh not hold of angels - He does not take their nature upon him. But he taketh hold of the seed of Abraham - He takes human nature upon him. St. Paul says the seed of Abraham, rather than the seed of Adam, because to Abraham was the promise made.
