John Calvin's Bible Commentary
Psalms 109:28
28.They shall curse. Interpreters are divided in their opinions about the meaning of these words. One class would render them as expressive of a desire or wish: Let them curse, provided that thou bless: let them arise, and be clothed with confusion Another class, and with them I readily agree, adopt the future tense of the indicative mood, They shall curse, etc. Should any prefer to understand the passage as indicating, on the part of the Psalmist, his resolution to suffer and submit to the curses of his enemies, I do not oppose their interpretation. In my opinion, however, those who view the words as a prayer, misinterpret them; because David, having already presented his petitions to God, and being secure in his favor, seems now rather to boast that their cursing will do him no harm; for Thou, says he, wilt bless me. By this means, he proves how little and how lightly he regarded the menaces of his enemies, though they might assail him by the poison of the tongue, and the power of the sword. From the example of David, let us learn to form the resolution of engaging God on our side, who can baffle all the designs of our enemies, and inspire us with courage to set at defiance their malice, wickedness, audacity, power, and fury.
And then, indeed, it is that the loving-kindness of God appears, when it banishes from our minds the fears which we entertain of the threatenings of the world. Therefore, relying upon the grace of God, boldly setting at nought the machinations and attacks of his enemies, believing that they could not prevail against God’s blessing, David raises the shout of triumph even in the midst of the battle. This truth is still more impressively inculcated in the succeeding clause of the verse: Though they arise, yet shall they be put to shame. By these words it is obviously his design to intimate that the ungovernable violence of his enemies is not yet subdued, but that he can endure all their fury and foam so long as the hand of God is stretched forth to maintain and defend him; and thus he animates and fortifies himself against all the pride of the world, and, at the same time, by his example emboldens all the faithful, so that they do not feel dejected even when the perverseness of their enemies seems to get the advantage over them, and to menace them with instant destruction. Cherishing such a hope, he trusts that, for the future, he shall be delivered from all his sorrows. Whence let us learn to bear patiently and meekly our trials, until the fit season and the full time, which God hath appointed, arrive for turning our weeping into joy. In the following verse he proceeds in the same strain of exultation, because, though he beholds the ungodly assuming a lofty air, yet, looking beyond the present state of things with the eye of faith, he entertains no doubt that God will frustrate all their designs, and pour contempt upon all their schemes.
