(9) Mountains, and all hills.--The invocation now alights on the crests of the highest mountains, and passes downward to the lower hills where vegetable life begins.

Fruitful trees.--Rather, fruit trees; the fruit-bearing tree being representative of one division of the vegetable world, planted and reared by man, the cedars of the other, which are (Psalm 104:16) of God's own plantation.

Verse 9. - Mountains, and all hills. The later psalmists are great admirers of" mountains." Perhaps the fiat and monotonous Babylonian plains led them to appreciate the beauties of a landscape like that of Palestine (comp. Psalm 83:14; Psalm 114:4, 6; Psalm 144:5; Psalm 147:8). Fruitful trees; rather, fruit trees; literally, trees of fruit. The Babylonian palms may have swept across the writer's remembrance; but probably the vine, the olive, and the fig, which were among the chief glories of Palestine, were in his mind principally. And all cedars. Babylonia had had no "cedars." When the exiles returned, the beauty of the cedar broke upon them as a sort of new revelation.

148:7-14 Even in this world, dark and bad as it is, God is praised. The powers of nature, be they ever so strong, so stormy, do what God appoints them, and no more. Those that rebel against God's word, show themselves to be more violent than even the stormy winds, yet they fulfil it. View the surface of the earth, mountains and all hills; from the barren tops of some, and the fruitful tops of others, we may fetch matter for praise. And assuredly creatures which have the powers of reason, ought to employ themselves in praising God. Let all manner of persons praise God. Those of every rank, high and low. Let us show that we are his saints by praising his name continually. He is not only our Creator, but our Redeemer; who made us a people near unto him. We may by the Horn of his people understand Christ, whom God has exalted to be a Prince and a Saviour, who is indeed the defence and the praise of all his saints, and will be so for ever. In redemption, that unspeakable glory is displayed, which forms the source of all our hopes and joys. May the Lord pardon us, and teach our hearts to love him more and praise him better.Mountains, and all hills,.... Which are originally formed by the Lord, and set fast by his power and strength; these are the highest parts of the earth, and are very ornamental and useful; they include all in them and upon them, the trees and herbage that grow upon them, gold, silver, brass, and iron in them; all very beneficial to mankind, and afford matter of praise to God for them; see Isaiah 55:12;

fruitful trees, and all cedars; trees bearing fruit are the fig trees, pomegranates, vines, and olives, with which the land of Canaan abounded; and such as bear lemons, oranges, plums, pears, apples, cherries, &c. which produce fruit for the use, pleasure, and delight of man, and so a means of praising God: and "cedars", the trees of the Lord which he hath planted; though they bear no fruit, yet very useful in building, and were of great service in the temple at Jerusalem; and which are put for all others of like usefulness, and minister just occasion of praise; see Psalm 96:12.
