Psalm 37:1-4 (KJV)
1 Fret not thyself because of evildoers, neither be thou envious against 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; so shalt thou dwell in the land, and verily thou shalt be fed.
4 Delight thyself also in the Lord: and he shall give thee the desires of thine heart.
