2:17 {16} Wherefore in {d} all things it behoved him to be made like unto [his] brethren, that he might be a {e} merciful and {f} faithful high priest in things [pertaining] to God, to make reconciliation for the sins of the people.
(16) He applies the same to the priesthood, for which he would not have been suited, unless he had become man, and like us in all things, sin being the exception.
(d) Not only concerning nature, but qualities too.
(e) That he might be truly touched with the feeling of our miseries.
(f) Doing his office sincerely.
2:17 It behoved him to be made like [his] brethren. Hence, for the reasons given above, it was necessary that he take our nature.
That he might be 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 reconciliation for the sins of the people. 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.
2:17 Wherefore it behoved him - It was highly fit and proper, yea, necessary, in order to his design of redeeming them. To be made in all things - That essentially pertain to human nature, and in all sufferings and temptations. Like his brethren - This is a recapitulation of all that goes before: the sum of all that follows is added immediately. That he might be a merciful and faithful High Priest - Merciful toward sinners; faithful toward God. A priest or high priest is one who has a right of approaching God, and of bringing others to him. Faithful is treated of, Heb 3:2, and c., with its use; merciful, Heb 4:14, and c., with the use also; High Priest, Heb 5:4, and c., Heb 7:1, and c. The use is added from Heb 10:19. In things pertaining to God, to expiate the sins of the people - Offering up their sacrifices and prayers to God; deriving God's grace, peace, and blessings upon them.
2:14-18 The angels fell, and remained without hope or help. Christ never designed to be the Saviour of the fallen angels, therefore he did not take their nature; and the nature of angels could not be an atoning sacrifice for the sin of man. Here is a price paid, enough for all, and suitable to all, for it was in our nature. Here the wonderful love of God appeared, that, when Christ knew what he must suffer in our nature, and how he must die in it, yet he readily took it upon him. And this atonement made way for his people's deliverance from Satan's bondage, and for the pardon of their sins through faith. Let those who dread death, and strive to get the better of their terrors, no longer attempt to outbrave or to stifle them, no longer grow careless or wicked through despair. Let them not expect help from the world, or human devices; but let them seek pardon, peace, grace, and a lively hope of heaven, by faith in Him who died and rose again, that thus they may rise above the fear of death. The remembrance of his own sorrows and temptations, makes Christ mindful of the trials of his people, and ready to help them. He is ready and willing to succour those who are tempted, and seek him. He became man, and was tempted, that he might be every way qualified to succour his people, seeing that he had passed through the same temptations himself, but continued perfectly free from sin. Then let not the afflicted and tempted despond, or give place to Satan, as if temptations made it wrong for them to come to the Lord in prayer. Not soul ever perished under temptation, that cried unto the Lord from real alarm at its danger, with faith and expectation of relief. This is our duty upon our first being surprised by temptations, and would stop their progress, which is our wisdom.
