Matthew Poole and continuators on Psalms 1:3

3 And he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season ; his leaf also shall not wither , and whatsoever he doth shall prosper .

Or, for, as this particle is oft used, as Psal. 60. 12. & 108. 13. Prov. 4. 17. This being the proof of that blessedness of a good man, which he had only asserted (v. i.)

(i. e.) A river; the plural number being put for the singular, as it is Iudg. 12. 7. Ionah 1. 5. and oft elsewhere.

(i. e.) In the time of fruit-bearing: Which being applyed to the good man, notes either, 1: His active goodness, that he seeketh and improveth all opportunities for the doing of good, exercising godlyness, justice, temperance, charity, patience, &c. according to the several occasions offered to him; or rather, 2: His certain prosperity and happiness, as may be gathered from the end of this verse, and the opposite state of the ungodly, v. 4. 5. That he shall have the fruit or benefit of his godly life in due time, or when it is expedient for him; possibly in this life, but assuredly in the next life.

His happiness is not short and transitory, as all worldly felicity is, but fixed and everlasting, like those trees which are continually green and flourishing: Or. and (like a tree) whose leaf never withers.

All his actions shall be crowned with success and a blessed end or effect; see Rom. 8. 28.
