Charles H. Spurgeon on Psalms 89:23

And I will beat down his foes before his face —crushing them and their plans. God himself thus fights the battles of his Son, and effectually overturns his foes. And plague them that hate him, or smite his haters. May none of us learn the terror of this threatening, which is surely being fulfilled upon all those unbelievers who have rejected the Son of God, and died in the hardness of their hearts. The prophecy is also having another fulfilment in the overthrow of systems of error, and the vexation caused to their promoters. There is no such plague to bad men as the prosperity of the cause of Jesus.
