Waterfall and Double Rainbow Over a Green Poolby emmanuel_higgins

Psalms 29:3

The voice of the LORD is upon the waters: the God of glory thundereth: the LORD is upon many waters.

The roar of thunder over the waters is the Lord's own voice, with the God of glory thundering above them. That voice is upon the waters as their ruler, exercising dominion over them. The thunder in the heavens is therefore the deliberate act of a living and personal God, not an impersonal force of nature. The power and majesty revealed in that ruling voice call for worship of Him.
