The Lord on high is mightier than the noise of many waters - That is, he is more powerful than those waters; he is able to control them. See Psalm 65:7, note; Job 38:11, note. The original here is more rapid in the course of the thought; more emphatic and forcible: "More than the voice of waters - many - mighty - the breakers of the sea - in the high place is Jehovah." He is over all those billows and breakers; more mighty than they all. They can proceed no further than he permits; they will be stayed when and where he commands. We can conceive of few things which more illustrate the power and the majesty of God than the fact that he thus presides over, and controls, the waves of the ocean.
Yea, than the mighty waves of the sea - The original word here corresponds precisely with our word "breakers" - the mighty waves that "break" on the beach.

The Lord - is mightier than the noise of many waters - Greater in strength than all the peoples and nations that can rise up against him.
Mighty waves of the sea - Even the most powerful empires can prevail nothing against him; therefore those who trust in him have nothing to fear.

The Lord on high is mightier than the noise of many waters,.... Christ is the most High; he is God over all, higher than the highest; he is, as King, higher than the kings of the earth; he is in the highest heavens, and higher than they; he is highly exalted, as Mediator, at the right hand of God: he is the mighty God, and mighty Saviour; yea, he is Almighty, and therefore mightier than all his enemies, and the noise they make, and the force they use; he is stronger than the strong man armed; than Satan, and all his principalities and powers; than all the persecuting princes and potentates of this world; than antichrist, and all the antichristian states: yea, than "the mighty waves of the sea"; the same are intended as before (c).
(c) Vide Homer. Iliad. 21. v. 190, 91. where the same is said of Jove, almost in the same words, and repeated as here.
