Fret not thyself because of evildoers, neither be thou envious against the workers of iniquity.
Rest in the LORD, and wait patiently for him: fret not thyself because of him who prospereth in his way, because of the man who bringeth wicked devices to pass.
Cease from anger, and forsake wrath:
fret not thyself in any wise to do evil.
~Psalm 37:1, 7, 8
