Proverbs 12:12

12 The godless lusteth after the spoil of evil-doers; But the root of the righteous shoots forth. This translation is at the same time an explanation, and agrees with Fleischer's "the godless strives by unrighteous gain like the wicked (Pro 4:14) to enrich himself, namely, as must be understood from the antithetic members of the parallelism, in vain, without thereby making progress and gaining anything certain. The preterite, as Pro 11:2, Pro 11:8, etc., places the general true proposition as a separate historic principle derived from experience. In 12b יתּן stands elliptically or pregnantly: edet, scil. quod radix edere solet, sobolem stirpis, ramorum, etc., as in the Arab. natan and ânatan are specially used without an obj. of the spontaneousness of an odour." מצוד (from צוּד, to spy, to hunt) is elsewhere the instrument of the hunt (a net), here the object and end of it. If the words had been מצוּדי רעים, then we would explain after מלאכי רעים, Psa 78:49 (vid., comm. on), and אושׁת רע, Pro 6:24; but in the difference of number, רעים will not be the qualitative but the subjective personal genitive: capturam qualem mali captant. Ewald, who understands ריקים, 11b, of good-for-nothing-fellows, interprets רעים here, on the contrary, as neuter (172b): the desire of the wicked is an evil net, i.e., wherein he catches all manner of evil for himself. The lxx has here two proverbs, in which מצוד occurs in the plur. and in the sense of ὀχυρώματα; 12b of the Hebr. text is rendered: αἱ δὲ ῥίζαι τῶν εὐσεβῶν ἐν ὀχρυώμασι, which Schleusner explains immotae erunt. The Hebr. text can gain nothing from this variation. That the lxx read ושׁרשׁ צדיקים איתן is not probable, since they nowhere thus translate איתן. But Reiske and Ziegler have, like Ewald and Hitzig, combined ית…

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 as effectually as he can!" He desires the strong-hold, or fortress, of evil men (so some read it), to act securely in doing mischief, that it may not turn upon him. 2. What is the care and aim of a good man: His root yields fruit, and is his strength and stability, and that is it that he desires, to do good and to be fixed and confirmed in doing good. The wicked desires only a net wherewith to fish for himself; the righteous desires to yield fruit for the benefit of others and God's glory, Rom 14:6.

12:12 The instability of thieves can produce violent behavior at any moment. By contrast, the godly are well rooted: Their relationships are stable even under duress.
