He watereth the hills from his chambers - The waters, as stated before, run in the valleys - in the natural channels made for them among the hills, Psalm 104:10. But still, it was a fact that the hills themselves were watered; that there were springs far up their heights; and that vegetation was sustained above the reach of the fountains and streams below; and it was a proof of the divine skill and beneficence that, in some way, water was furnished on the summits and sides of the hills themselves. This was caused, the psalmist says, by God's pouring water on them, as it were, from his own "chambers" - his abode on high. The allusion is, doubtless, to rain, which seems to be poured down from the very abode of God. The word rendered "chambers" means "upper rooms," (see the notes at Psalm 104:3); and the reference is to the dwelling-place of God, as far above the earth.
The earth is satisfied with the fruit of thy works - Thy doings; with what thou hast done. All the needs of the earth seem to be met and "satisfied;" all that it could desire to make it fertile and beautiful; and the proper abode of man, of beast, and of fowl, has been granted. It has no cause of complaint; nothing has been left undone, in the valleys or on the hills, on the dry land or in the waters, that was needful to be done to carry out the purpose for which it has been called into being.

From his chambers - The clouds, as in Psalm 104:3.
The earth is satisfied - The inhabitants of it.

He watereth the hills from his (g) chambers: the earth is satisfied with the fruit of thy works.
(g) From the clouds.

He watereth the hills from his chambers,.... The house of his superior treasures, as the Targum. The airy regions, Psalm 104:3 with the clouds of heaven, by the rain which they drop down upon them; the usefulness of which blessings of nature is largely described in this and some following verses. "The hills", which are naturally dry and barren, and receive but little advantage from the springs, fountains, and rivers below, are supplied with water from above; and become fruitful, bear herbage, and are clothed with flocks. This seems to refer to the first rain that was upon the earth, Genesis 2:5 and which favour is continued to all lands, excepting some part of the land of Egypt, and in all ages since; see Psalm 65:9. So ministers of the word, who are set in the first place, and are eminent in the church of God, and who water others, are watered themselves with the gifts and graces of the Spirit descending from above, as the apostles were, in an extraordinary manner, at the day of Pentecost; and as others in a more ordinary manner daily are. So likewise the churches of Christ, comparable to hills and mountains for firmness and visibility, and the several members thereof, are watered with the dews of divine favour, with the rain of the divine word; which comes down from heaven as the rain does, and drops and distils like that; and with the grace of the divine Spirit, whereby their souls become as a watered garden, whose springs fail not.
The earth is satisfied with the fruit of thy works; with the fruits which grow out of it by means of rain, as are after mentioned; herbs, grass, and trees, so Aben Ezra: or with the influences of the heavens, which are the work of God's hands, and by which the earth is made fruitful; or more particularly with the virtue and efficacy of the rain, so Kimchi; which is the Lord's peculiar work, Jeremiah 14:22. This the earth drinking in, is as satisfied with as a thirsty man is with drinking a draught of water; see Deuteronomy 11:11. So the people of God, comparable to the good earth that drinks in the rain that often comes upon it, are satisfied with the love of God, with the blessings of his grace, with the doctrines of his Gospel, and with the ordinances of his house.

The hills - Which most need moisture. From - From the clouds. Satisfied - By this means all the parts of the earth, are made fruitful. The fruit - With the effects of those sweet showers.
