VI. The trees that were on the banks of this river—many trees on the one side and on the other (v. 7), which made the prospect very pleasant and agreeable to the eye; the shelter of these trees also would be a convenience to the fishery. But that is not all (v. 12); they are trees for meat, and the fruit of them shall not be consumed, for it shall produce fresh fruit every month. The leaf shall be for medicine, and it shall not fade, This part of the vision is copied out into St. John's vision very exactly (Rev. xxii. 2), where, on either side of the river, is said to grow the tree of life, which yielded her fruit every month, and the leaves were for the healing of the nations. Christians are supposed to be these trees, ministers especially, trees of righteousness, the planting of the Lord (Isa. lxi. 3), set by the rivers of water, the waters of the sanctuary (Ps. i. 3), grafted into Christ the tree of life, and by virtue of their union with him made trees of life too, rooted in him, Col. ii. 7. There is a great variety of these trees, through the diversity of gifts with which they are endued by that one Spirit who works all in all. They grow on the bank of the river, or they keep close to holy ordinances, and through them derive from Christ sap and virtue. They are fruit-trees, designed, as the fig tree and the olive, with their fruits to honour God and man, Judg. ix. 9. The fruit thereof shall be for meat, for the lips of the righteous feed many. The fruits of their righteousness are one way or other beneficial. The very leaves of these trees are for medicine, for bruises and sores, margin. Good Christians with their good discourses, which are as their leaves, as well as with their charitable actions, which are as their fruits, do good to those about them; they strengthen the weak, and bind up the broken-hearted. Their cheerfulness does good like a medicine, not only to themselves, but to others also. They shall be enabled by the grace of God to persevere in their goodness and usefulness; their leaf shall not fade, or lose its medicinal virtue, having not only life in their root, but sap in all their branches; their profession shall not wither (Ps. i. 3), neither shall the fruit thereof be consumed; that is, they shall not lose the principle of their fruitfulness, but shall still bring forth fruit in old age, to show that the Lord is upright (Ps. xcii. 14, 15), or the reward of their fruitfulness shall abide for ever; they bring forth fruit that shall abound to their account in the great day, fruit to life eternal; that is indeed fruit which shall not be consumed. They bring new fruit according to their months, some in one month and others in another: so that still there shall be one or other found to serve the glory of God for the purpose he designs. Or each one of them shall bring forth fruit monthly, which denotes an abundant disposition to fruit-bearing (they shall never be weary of well-doing), and a very happy climate, such that there shall be a perpetual spring and summer. And the reason of this extraordinary fruitfulness is because their waters issued out of the sanctuary; it is not to be ascribed to any thing in themselves, but to the continual supplies of divine grace, with which they are watered every moment (Isa. xxvii. 3); for, whoever planted them, it was that which gave the increase.
