Psalms 75:4

4.I said to the fools, Act not foolishly. (255) After he has set the office of God full in his own view and in the view of the faithful, he now triumphs over all the ungodly, whom he impeaches of madness and blind rage, the effect of their despising God, which leads them to indulge to excess in pride and self-gloriation. This holy boasting to which he gives utterance depends upon the judgment, which in the name of God he denounced to be at hand; for when the people of God expect that he is coming to execute judgment, and are persuaded that he will not long delay his coming, they glory even in the midst of their oppressions. The madness of the wicked may boil over and swell with rage, and pour forth floods to overwhelm them; but it is enough for them to know that their life is protected by the power of God, who can with the most perfect ease humble all pride, and restrain the most daring and presumptuous attempts. The faithful here deride and despise whatever the wicked plot and conspire to execute, and bid them desist from their madness; and in calling upon them to do this, they intimate that they are making all this stir and commotion in vain, resembling madmen, who are drawn hither and thither by their own distempered imaginations. It is to be observed, that the Psalmist represents pride as the cause or mother of all rash and audacious enterprises. The reason why men rush with such recklessness upon unlawful projects most certainly is, that blinded by pride, they form an undue and exaggerated estimate of their own power. This being a malady which is not easily eradicated from the hearts of men, the admonition, Lift not up your horn on high (256) is repeated once and again. They are next enjoined not to speak with a fat or a stiff neck; by which is meant that they should not speak harshly and injuriously; (257) for it is usual with proud persons to erect the neck and raise the head when they pour forth their menaces. Others translate the words, Speak not stiffly with your neck; but the other translation is the more correct.
