Psalm 75:3BSB·traditional attribution

When the earth and all its dwellers quake, it is I who bear up its pillars. Selah

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

The earth and all the inhabitants thereof are dissolved. When anarchy is abroad, and tyrants are in power, everything is unloosed, dissolution threatens all things, the solid mountains of government melt as wax; but even then the Lord upholds and sustains the right. I bear up the pillars of it. Hence, there is no real cause for fear.

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.
