Charles H. Spurgeon on Psalms 76:10

The remainder of wrath shalt thou restrain. The remainder of wrath, i.e. what is left behind of the wrath of men, when God has glorified himself thereby. Even after God has defeated the purposes of wicked men, and made them contribute to his glory, yet there is abundance of wrath remaining. But what becomes of that wrath that is left? God shall restrain it. The word signifies to gird up. However God may see fit to slacken the bridle of his providence, and suffer wicked men to vent their wrath and enmity, as far as it shall contribute to his glory; yet the super abounding and the remainder of his wrath that is not for his glory and his people's profit, God will gird it up, that they shall not get it vented... If any wrath of man remain beyond what shall bring in a revenue of praise unto God, he will restrain it, and bind it up like the waters of a mill: he will suffer as much of the current of water to run upon the wheel, as serves to carry it about and grind his corn, but the remainder of the water he sets it off another way: so God will let out as much of the current of man's wrath as shall serve the ends of his glory and our good, but the remainder of the stream and current he will restrain, and turn another way. In Isaiah 28 we are told that God will not be aye "threshing his corn, nor break it with the wheel of his cart, nor bruise it with his horsemen. This cometh forth from the Lord of hosts, which is wonderful in counsel, and excellent in working." All this comfort is sure and certain, there is not the least peradventure about it, that the flame of man's wrath shall praise the Lord, and the superfluous fire shall be quenched, or hemmed in; for here we have God's parole of honour for it: Surely the wrath of man shall praise thee: the remainder of wrath shalt thou restrain.
