Charles H. Spurgeon on Psalms 104:16

The trees of the Lord. The transition which the prophet makes from men to trees is as if he had said, It is not to be wondered at, if God so bountifully nourishes men who are created after his own image, since he does not grudge to extend his care even to trees. By "the trees of the Lord", is meant those which are high and of surpassing beauty; for God's blessing is more conspicuous in them. It seems scarcely possible for any juice of the earth to reach so great a height, and yet they renew their foliage every year. John Calving.
