Do not fret because of those who are evil
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.
Take delight 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 do this:
He will make your righteous reward shine like the dawn,
your vindication like the noonday sun.
Be still before the Lord
and wait patiently for him;
do not fret when people succeed in their ways,
when they carry out their wicked schemes.
The salvation of the righteous comes from the Lord;
he is their stronghold in time of trouble.
The Lord helps them and delivers them;
he delivers them from the wicked and saves them,
because they take refuge in him.
Psalm 37:1-7, 39-40
