Charles H. Spurgeon on Psalms 104:8

The vanquished waters are henceforth obedient. They go up by the mountains, climbing in the form of clouds even to the summits of the Alps. They go down by the valleys unto the place which thou hast founded for them: they are as willing to descend in rain, and brooks, and torrents as they were eager to ascend in mists. The loyalty of the mighty waters to the laws of their God is most notable; the fierce flood, the boisterous rapid; the tremendous torrent, are only forms of that gentle dew which trembles on the tiny blade of grass, and in those ruder shapes they are equally obedient to the laws which their Maker has impressed upon them. Not so much as a solitary particle of spray ever breaks rank, or violates the command of the Lord of sea and land, neither do the awful cataracts and terrific floods revolt from his sway. It is very beautiful among the mountains to see the divine system of water supply —the rising of the fleecy vapours, the distillation of the pure fluid, the glee with which the newborn element leaps down the crags to reach the rivers, and the strong eagerness with which the rivers seek the ocean, their appointed place.
