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 Psalms 96:12.
