For he shall be as a tree planted by the waters,.... Not as a "heath or shrub", but as a "tree", a green olive tree, a palm tree, a cedar in Lebanon, a fruitful flourishing tree; and he is one that really is a tree of righteousness, that is filled with the fruits of righteousness; and not like one of the trees of the wood, that grows wild, or as a wild olive tree, but as one "planted" in a garden, vineyard, or field; and is one that is planted in Christ, in the likeness of his death and resurrection, and in the house of the Lord; and that not only by means of the ingrafted word, and of Gospel ministers, who plant and water instrumentally; but by the Lord himself, as the efficient cause; and therefore called "the planting of the Lord"; and such plants as shall never be plucked up, Isa 60:21 and not like the earth in the wilderness, or trees in dry and barren soils; but like such that are planted "by the waters", which run about their roots, and make them fruitful; by which may be meant the love of God, and the streams of it; the fulness of grace in Christ, and the word and ordinances, the still waters of the sanctuary, Ps 23:2:and that spreadeth out her roots by the river; and which is the cause of the spreading of them: such an one is rooted in Christ, and in the love of God, which is as a river; with which being watered, he casts out his roots as Lebanon, as the cedars there; and is both firm and fruitful; see Ho 14:5:and shall not see when heat cometh; shall perceive it, nor be affected with it, being planted so near a river: or "shall not fear"; which is the Cetib, or writing of the Hebrew text; and is followed by the Septuagint, Syriac, and Arabic versions; though the Keri, or marginal reading, is, "shall not see"; which is followed by the Targum, and by us, and others.
The man that trusts in the Lord, he is not afraid of the heat of persecution when it comes, nor is he hurt by it; he does not perceive it, but grows the more under it; when a hypocrite and formal professor is withered by it; see Mt 13:6:but her leaf shall be green; neither fail, nor lose its colour: a profession of faith is held without wavering; there being a radical moisture, the truth of grace, a well of living water, springing up into everlasting life, to supply and support it:and shall not be careful in the year of drought; for lack of moisture, having a sufficiency.
