Fret not yourself because of evil doers;
be not envious of wrongdoers!
For they will soon fade like the grass
and wither like the green herb.
Trust in the Lord, and do good;
dwell in the land and befriend faithfulness.
Delight yourself in the Lord,
and He will give you the desires of your heart.
Commit your way to the Lord;
trust in Him and He will act.
He will bring forth your righteousness as the light,
and your justice as the noonday.
Be still before the Lord and wait patiently for him;
fret not yourself over the one who prospers in his way,
over the man who carries out evil devices!
Refrain from anger, and forsake wrath!
Fret not yourself; it tends only to evil.
For the evildoers shall be cut off,
but those who wait for the Lord shall inherit the land.
Psalm 37:1-9, ESV
