Charles H. Spurgeon on Psalms 96:12

Let the field be joyful, and all that is therein. Let the cultivated plains praise the Lord. Peace enables their owners to plough and sow and reap, without fear of the rapine of invaders, and therefore in glad notes they applaud him whose empire is peace. Both men, and creatures that graze the plain, and the crops themselves are represented as swelling the praises of Jehovah, and the figure is both bold and warranted, for the day shall come when every inhabited rood of ground shall yield its song, and every farmstead shall contain a church. Then shall all the trees of the wood rejoice. He does not say, let them rejoice, but they shall do so. The faith of the psalmist turns itself from the expression of desire to the fully assured prediction of the event. Groves have in old times stood shuddering at the horrid orgies which have been performed within their shade, the time shall come when they shall sing for joy because of the holy worship, the sounds of which they shall hear. The bush is the stronghold of savage men and robbers, but it shall be sanctified to retirement and devotion. Perhaps the psalmist was thinking of the birds; so Keble must have supposed, for he versifies the passage thus —

"Field exults and meadow fair,

With each bud and blossom there,

In the lonely woodlands now

Chants aloud each rusting bough."
