Psalms 75:9,10 - Joseph Benson’s Commentary on the Old and New Testaments

But I will declare for ever These dispensations of mercy and judgment to the world. I will sing praises to the God of Jacob He will praise God, and give him glory for the power to which he had advanced him, and that not only at first, while the mercy was fresh, but for ever; as long as he lives he will remember, and be grateful for, this instance of the Lord's goodness. Thus the exaltation of the Son of David will be the subject of the saints' everlasting praises. And he will give glory to God, not only as his God, but as the God of Jacob, knowing it was for his servant Jacob's sake, and because he loved his people Israel, that he made him king over them. All the horns of the wicked Their honour and power, which they made instruments of mischief to oppress good men; a metaphor taken from horned and mischievous beasts; will I cut off I will humble their pride and break their power; I will disable them to do mischief. But the horns of the righteous shall be exalted Good men shall be encouraged and promoted, and intrusted with the management of all public affairs, which will be a great blessing to all my people. Thus he determines to use the power wherewith he was intrusted for the great ends for which it was put into his hands, as every governor ought to do, and as every good governor will do. And herein David was a type of Christ, who, with the breath of his lips, slays the wicked, Isaiah 11:4; but exalts with honour the horn of the righteous, Psalms 112:9.
