John Gill's Exposition of the Whole Bible
Psalms 109:28
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 2 Samuel 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, Daniel 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, Psalms 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, Psalms 16:11.
