Ezekiel 47:12 Douay-Rheims

And by the torrent on the banks thereof on both sides shall grow all trees that bear fruit: their leaf shall not fall off, and their fruit shall not fail: every month shall they bring forth firstfruits, because the waters thereof shall issue out of the sanctuary: and the fruits thereof shall be for food, and the leaves thereof for medicine.

“month after month its fruits will ripen From month to month its fruits will ripen. for a cure [Heb. לִתְרוּפָה.] Our Sages of blessed memory explained: to unlock the mouth (לְהָתִיר פֶה) of the dumb and the mouth [of the womb] of the barren (Men. 98a), but its apparent meaning is a word for healing, as in (Jer. 6:14): “And they healed (וַיְרַפְאוּ) the breach of My people easily.” And so did Menahem connect it.”

“And by the river on the banks thereof, on this side and on that side,.... On each side of the river, on the banks of it: shall grow all trees for meat; such as bear fruit, that may be eaten, and is good for food: by these "trees" are meant truly gracious souls, converted persons, real Christians, true believers in Christ; who like trees have a root, are rooted in the love of God, in the person and grace of Christ, and have the root of the matter in them, the grace of the blessed Spirit; and who also is their sap, of which they are full, and so grow in grace, and in the knowledge of Christ; grow up in him, and grow upwards and heavenwards in their affections and desires, and in the exercise of faith and hope: they are the trees of the Lord, trees of righteousness, good trees, that bring forth good fruit; and are often in Scripture compared to trees the most excellent, as palm trees, cedars, olives, myrtles, &c. and wherever the Gospel comes, these trees arise, and are watered and made fruitful by it; sometimes in lesser, and sometimes in greater numbers, as in the first times of the Gospel, and as they will in the latter day; see Psa 92:12, whose leaf shall not fade; as the leaves of trees in autumn do, and drop off and fall; to which some professors of religion are compared, who bear no fruit, only have the leaves of a profession, and this they drop when any trouble or difficulty arises, Jde 1:12, but true believers, as they take up a profession on principles of grace, they hold it fast without wavering; their root, seed, and sap, remain, and so never wither and die in their profession; see Psa 1:3, neither shall the fruit thereof be consumed; which are the graces of the Spirit, and good works flowing from them: the graces of the Spirit are abiding ones, as faith, hope, and love; these never die, are an incorruptible seed, a well of water springing up unto everlasting life; and good works, which are fruits meet for repentance, and evidences of faith, and by which trees are known to be good, always continue to be wrought by believers, in the strength and grace of Christ, from whom they have all their fruits of every kind, Hos 14:8, it shall bring forth new fruit according to his months; or, "first fruits" (o); that is, everyone of these trees, or every true believer, shall be continually in the exercise of grace, and the performance of duty; they shall be constant and immovable, always abounding in the work of the Lord; they shall never cease from yielding fruit, or doing good; they shall still bring it even in old age; see Psa 92:14, because their waters they issued out of the sanctuary; because the waters, which issued out of the sanctuary, ran by these trees, and watered them, and made them fruitful, and therefore called their waters: the fruitfulness of these trees, true believers, is not owing to themselves, to their free will and power; to their own industry, diligence, and cultivation; but to the supplies of grace they receive by means of the Gospel, and the doctrines of it; which bring forth, or cause to bring forth fruit, wherever they come with power, Col 1:6, and the fruit thereof shall be for meat; not for saints themselves, who live not, neither on their graces, nor their works; though indeed they do eat the fruits of their doings, Isa 3:10, that is, enjoy good things, consequent on their works, through the free favour and good will of God; but for meat for others; for their fruit, which appears in their words and actions, are very beneficent to others; their fruit is a tree of life, Pro 11:30 and their lips feed many, Pro 10:21, with knowledge and understanding; with the Gospel, and the doctrines of it; and with the comfortable experience they have of its truths and promises: yea, their fruit are meat and food for Christ himself; who comes into his garden, and eats his pleasant fruits, feeds and feasts, and delights himself with his own grace in his people, and the exercise of it, Sol 4:9, and the leaf thereof for medicine; or, "for bruises" (p); for the healing of them, which is only done by the blood of Christ; who is the only physician, the sun of righteousness, that rises with healing or pardon in his wings; and the whole language of this passage is borrowed from hence by John, and applied to Christ the tree of life, Rev 22:2 and the Gospel professed by true believers directs to him for healing, or for the remission of sin, and is the means of applying it, Psa 107:20 and a cheerful constant profession of Christ and his Gospel, which is the Christian's leaf, does good like a medicine, both to the Christian himself, and to others; who are animated and encouraged thereby to go on with pleasure in the ways of God. (o) "afferet primitiva", V. L. Vatablus; "primogenita", Starckius. So Ben Melech. (p) "ad contritionem, vel ad sanitatem contritionis", Vatablus; "ad fractionem sanandam", Pagninus. So Ben Melech.”

“Shall grow all trees for meat, whose leaf shall not fade - A description that suits the righteous, who are still producing - 1. The fruits of faith. 2. The fruits of the Spirit. 3. The fruits of love to God, obedience to his holy will, and love to all men. Benevolence, mercy, charity, kindness, etc. The leaf thereof for medicine - See Rev 22:1-5. Even the leaves, the holy profession of the righteous, is a spiritual medicine. Righteousness is thus encouraged in the world. The profession points out the salvation, as it shows the nature and sufficiency of that salvation; for a just creed contains all the articles of the Christian faith.”

“First-fruits, or most excellent. (Haydock) — St. John saw such (Worthington) a tree of life, Apocalypse xxii. (Haydock) — The doctrine of the gospel, and the study of the sacred books, have the most salutary effects; while the very leaves, or the example of the saints, heal the soul. No more shall the deceitful fruits near Sodom be seen (Calmet) beautiful, but full of nothing but ashes. (Tacitus, An. v.) — Where Christ instructs, a torrent of grace and glory is presently formed. Like the mustard seed growing into a large tree, in which the birds rest, its origin is mean; yet its progress is grand and astonishing.”

“Instead of the "vine of Sodom and grapes of Gomorrah" (Deu 32:32), nauseous and unwholesome, trees of life-giving and life-restoring virtue shall bloom similar in properties to, and exceeding in number, the tree of life in Eden (Rev 2:7; Rev 22:2, Rev 22:14). leaf . . . not fade--expressing not only the unfailing character of the heavenly medicine of the tree of life, but also that the graces of the believer (as a tree of righteousness), which are the leaves, and his deeds, which are the fruits that flow from those graces, are immortal (Psa 1:3; Jer 17:8; Mat 10:42; Co1 15:58). new fruit--literally, "firstlings," or first fruit. They are still, each month afresh, as it were, yielding their first-fruit [FAIRBAIRN]. The first-born of a thing, in Hebrew idiom, means the chiefest. As Job 18:13, "the first-born of death," that is, the most fatal death.”
