Psalm 37

Do not fret because of evil men
or be envious of those who do wrong;
for like the grass they will soon wither,
like green plants they will soon die away.

Trust in the LORD and do good;
dwell in the land and enjoy safe pasture.
Delight yourself in the LORD
and he will give you the desires of your heart.

Ps 37:1-4 (NIV)
