Psalm 37:1-4

FRET NOT yourself because of evildoers, neither be envious against those who work unrighteousness (that which is not upright or in right standing with God). For they shall soon be cut down like the grass, and wither as the green herb. Trust (lean on, rely on, and be confident) in the Lord and do good; so shall you dwell in the land and feed surely on His faithfulness, and truly you shall be fed. Delight yourself also in the Lord, and He will give you the desires and secret petitions of your heart.
