I say to the proud, ‘Do not boast,’ and to the wicked, ‘Do not lift up your horn.

John Calvin Reformed @genevareformer

PSALM 75 It affords matter of rejoicing and thanksgiving to the whole Church, to reflect that the world is governed exclusively according to the will of God, and that she herself is sustained by his grace and power alone. Encouraged by this consideration, she triumphs over the proud despisers of God, who, by their infatuated presumption, are driven headlong into all manner of excess. To the chief musician. Destroy not.

C.H. Spurgeon Reformed Baptist @princeofpreachers

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.

Matthew Henry Presbyterian @wholebiblehenry

In these verses, I. The psalmist gives to God the praise of his advancement to honour and power, and the other great things he had done for him and for his people Israel (Psa 75:1): Unto thee, O God! do we give thanks for all the favours thou hast bestowed upon us; and again, unto thee do we give thanks; for our thanksgivings must be often repeated.
