Matthew Henry's Complete Bible Commentary

Verse 10

See here the character of a very wicked man. 1. The strong inclination he has to do mischief. His very soul desires evil, desires that evil may be done and that he may have the pleasure, not only of seeing it, but of having a hand in it. The root of wickedness lies in the soul; the desire that men have to do evil, that is the lust which conceives and brings forth sin. 2. The strong aversion he has to do good: His neighbour, his friend, his nearest relation, finds no favour in his eyes, cannot gain from him the least kindness, though he be in the greatest need of it. And, when he is in the pursuit of the evil his heart is so much upon, he will spare no man that stands in his way; his next neighbour shall be used no better than a stranger, than an enemy. MHBCC 650.10
