Psalms 93:3

The floods have lifted up, O Lord, the floods have lifted up their voice - The word here rendered “floods,” means properly rivers, and then it may be applied to any waters. The word voice here refers to the noise of raging waters when they are agitated by the winds, or when they dash on the shore. See the notes at Psalms 42:7.

The floods lift up their waves - As if they would sweep everything away. The allusion here is to some calamity or danger which might, in its strength and violence, be compared with the wild and raging waves of the ocean. Or if it refers literally to the ocean in a storm, then the psalm may have been the reflections of the author as he stood on the shore of the sea, and saw the waves beat and dash against the shore. To one thus looking upon the billows as they roll in toward the shore, it seems as if they were angry; as if they intended to sweep everything away; as if the rocks of the shore could not resist them. Yet they have their bounds. They spend their strength; they break, and retire as if to recover their force, and then they renew their attack with the same result. But their power is limited. The rocky shore is unmoved. The earth abides. God is over all. His throne is unshaken. No violence of the elements can affect that; and, under his dominion, all is secure.
