This psalm contains an oracle David received from the Lord concerning the wicked. In contrast to them, he rejoiced in the loyal love and righteousness of God.
"This is a psalm of powerful contrasts, a glimpse of human wickedness at its most malevolent, and divine goodness in its many-sided fullness. Meanwhile the singer is menaced by the one and assured of victory by the other. Few psalms cover so great a range in so short a space."90
