John Wesley
They search out iniquities; they accomplish a diligent search: both the inward thought of every one of them, and the heart, is deep.
Iniquities — They study diligently, to find new ways of doing mischief.
Deep — Cunning, both to contrive and conceal, and to execute their plots.
So they shall make their own tongue to fall upon themselves: all that see them shall flee away.
Flee — Through fear of being involved in their destruction.
The righteous shall be glad in the LORD, and shall trust in him; and all the upright in heart shall glory.
Glad — For the honour of God, which by this means is vindicated.
