John Trapp Complete Commentary
Proverbs 12:5
The thoughts of the righteous [are] right: [but] the counsels of the wicked [are] deceit.
Ver. 5. The thoughts of the righteous are right.] He feeds his thoughts upon the best objects, those especially mentioned in that little Bible, Philippians 4:8, "Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these Things."if worse break in, as they will, he jostles them out, and rids the room of them. See Trapp on " Pro 11:23 "
But the counsels of the wicked are deceit.] Not their rash thoughts only, but also their deliberate ones are how to circumvent others, or to cloak their own wickedness. "Every imagination," the whole frame, "of their thoughts is evil, only evil, and continually evil." Genesis 6:5 ; Gen 8:21 If good thoughts look into a wicked heart, they stay not there, as those that like not their lodging: the flashes of lightnings may be discerned into the darkest prisons. The light that shines into a holy heart is constant, like that of the sun, which keeps due times, and varies not the course for any of these sublunary occasions.
