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.
