A meditation on Ps 37:1-8 “Do not fret it only causes harm”

Do not fret because of evildoers,
Nor be envious of the workers of iniquity.

2 For they shall soon be cut down like the grass,
And wither as the green herb.

3 Trust in the LORD, and do good;
Dwell in the land, and feed on His faithfulness.

4 Delight yourself also in the LORD,
And He shall give you the desires of your heart.

5 Commit your way to the LORD,
Trust also in Him,
And He shall bring it to pass.

6 He shall bring forth your righteousness as the light,
And your justice as the noonday.

7 Rest in the LORD, and wait patiently for Him;
Do not fret because of him who prospers in his way,
Because of the man who brings wicked schemes to pass.

8 Cease from anger, and forsake wrath;
Do not fret—it only causes harm.
