Fret not thyself because of evil-doers, Neither be thou envious against them that work unrighteousness.
For they shall soon be cut down like the grass, And wither as the green herb.
Trust in Jehovah, and do good; Dwell in the land, and feed on his faithfulness.
Delight thyself also in Jehovah; And he will give thee the desires of thy heart. Commit thy way unto Jehovah; Trust also in him, and he will bring it to pass.
And he will make thy righteousness to go forth as the light, And thy justice as the noonday.
Rest in Jehovah, and wait patiently for him: Fret not thyself because of him who prospereth in his way, Because of the man who bringeth wicked devices to pass.Psalms 37:1-7 ASV
Of course, it must be admitted that Old Testament writers indeed had much less information than Christians about such things; but the psalmist’s words as they appear in this chapter are fully adequate. “His faith that infinite love rules the universe, that righteousness is always gain, and that wickedness is always loss is grandly and eternally true.”
Also, it should be pointed out that faith in the resurrection of the dead belonged to all the Old Testament saints.
Psalm 37 teaches that the prosperity of the wicked is superficial and temporary, and that those who trust in God may be certain that, finally, they will be the ones who are blessed.
Every Christian, at one time or another, has marvelled at the success and prosperity of men who are openly profane and wicked; and it is that problem with which the psalmist is dealing.
God’s people are repeatedly warned not to “fret.” That means not to become irritated, angry, disturbed, or upset by what must appear to many as an injustice.
The caution is that we should,`wait,’ `trust in the Lord,’ `commit our way unto God,’ and `rest’ in Him. And what will God do?
These are among the most magnificent promises in the Bible, and God’s people can afford to trust them.
