Mountains, and all hills; fruitful trees, and all cedars:
Ver. 9. Mountains, and all hills] These praise God by their form, hugeness, fruits, prospects, &c.
Fruitful trees] These, by the variety of their natures and fruits, do notably set forth the wisdom, power, and goodness of the Almighty; while they spend themselves and the principal part of their sap and moisture in bringing forth some pleasant berry, or the like, for the use of man, who is thereby engaged to bless God.
