Solomon
Proverbs 12:12ESV·traditional attribution

Whoever is wicked covets the spoil of evildoers, but the root of the righteous bears fruit.

Matthew Henry Presbyterian

See here, 1. What is the care and aim of a wicked man; he would do mischief: He desires the net of evil men. "Oh that I were but as cunning as such a man, to make a hand of those I deal with, that I had but his art of over-reaching, that I could but take my revenge on one I have spite to...

John Gill Reformed Baptist

The wicked desireth the net of evil men,.... To be master of all the wicked arts and methods evil men use to ensnare and oppress others; to get them and their substance into their hands; or "desireth the evil net", as the Targum; the evil net of antichrist, which he lays for the poor, whom he draws into it and catches them; see Psa 10:9.

Jamieson-Fausset-Brown Reformed

the wicked . . . evil--They love the crafty arts of deception. the root . . . fruit--their own resources supply them; or, it may be rendered: "He (God) giveth, or, sets (Eze 17:22) the root of the righteous," and hence it is firm: or, the verb is impersonal; "As to the root . . . it is firm" (Pro 17:19).
