Psalms 104:13 - Exposition

He ( i.e. God) watereth the hills from his chambers (comp. Psalms 104:3 ). The mountains themselves, even their highest tops, are not left dry. Where springs cannot reach, rain falls from God's "chambers" in the sky, and spreads equal refreshment. The earth is satisfied with the fruit of thy works. The whole earth—mountains, hills, plains, valleys—is thus "satisfied," i.e. sufficiently supplied with water, by the means which God has elaborated.
