Charles H. Spurgeon on Psalms 75:4

I said unto the fools, Deal not foolishly. The Lord bids the boasters boast not, and commands the mad oppressors to stay their folly. How calm is he, how quiet are his words, yet how divine the rebuke. If the wicked were not insane, they would even now hear in their consciences the still small voice bidding them cease from evil, and forbear their pride. And to the wicked, Lift not up the horn. He bids the ungodly stay their haughtiness. The horn was the emblem of boastful power; only the foolish, like wild and savage beasts, will lift it high; but they assail heaven itself with it, as if they would gore the Almighty himself. In dignified majesty he rebukes the inane glories of the wicked, who beyond measure exalt themselves in the day of their fancied power.
