“"And let them know how that this is Thy Hand, and that Thou, Lord, hast made it" (ver. 26). He said, "Let them know," of those for whom He even prayed while they were raging; for even those who afterwards believed in Him were among the crowd who shook their heads in mockery of Him. But let those who ascribe unto God the shape of the human body, learn in what sense God hath a hand. Let us therefore understand, that the Hand of God meaneth Christ: whence it is elsewhere said, "Unto whom is the arm of the Lord revealed?" ...”

“"Though they curse, yet bless Thou" [Psalm 109:27]. Vain therefore and false is the cursing of the sons of men, that have pleasure in vanity, and seek a lie; but when God blesses, He does what He says. "Let them be confounded that rise up against me." For their imagining that they have some power against Me, is the reason that they rise up against Me; but when I shall have been exalted above the heavens, and My glory shall have commenced spreading over the whole earth, they shall be confounded. "But Your servant shall rejoice:" either on the right hand of the Father, or in His members when they rejoice, both in hope among temptations, and after temptations for evermore.”

“Let them curse, but bless thou,.... Let them curse me, as Shimei did David, the type of Christ; let them curse themselves, as they did; or my people: or "let them be cursed", as the Syriac version; cursed in life and at death, and to all eternity: but "bless thou me", the Messiah; as he did, when he raised him front the dead, set him at his right hand, and gave him a name above everyone, and made him most blessed for evermore; and bless my people with all spiritual blessings of grace, and with eternal glory and happiness. Or "be thou blessed"; let honour, blessing, and praise, be continually ascribed to thee; if God does but bless, it is no matter if wicked men curse, so Aben Ezra and Kimchi interpret it; see Sa2 16:11. When they arise, let them be ashamed; be suffered to do those things which may bring shame and disgrace upon them; or let them be disappointed and so confounded, as the Jews were; who though they so far gained their point as to bring Christ to the dust of death and the grave, yet to their great confusion he arose again from the dead; or let them be ashamed at the last day, as they will be when Christ shall come in the clouds of heaven and be their Judge, who will then be glad to shelter themselves in rocks and caves. This is imprecated to be done when they shall arise: rise up against Christ to take away his life; rise up against his disciples to persecute them, against his Gospel to contradict and blaspheme it, and against his cause and interest to crush it; or against the Romans, to shake off their yoke, when they were brought to great shame and confusion; or when they shall arise at the resurrection of the dead, which will be to shame and everlasting contempt, Dan 12:2. But let thy servant rejoice; the Messiah, who appeared in the form of a servant; came not as a temporal lord and prince, to be ministered unto, but as a servant, to minister to others; and who is a servant of God's choosing, calling, and sending, and whom he faithfully served; and who, as prayed for, did rejoice in the strength of the Lord, given him as man; and in the salvation wrought for and by him, Psa 21:1, in the work of the Lord prospering in his hand; in his victory over sin, Satan, the world, and death; in the presence of God he was made glad with, and in the glory promised him, which he had with his Father before the world was, Psa 16:11.”
