Psalm 37 is a wisdom psalm dealing with themes presented in what we call the Wisdom Literature. In particular, Psalm 37 addresses the problem caused when godless people prosper. It contrast, it is better to stay faithful to God, which is expressed in contentment, honest dealing, generosity, and just speech. The LORD will make a distinction between the wicked and faithful in his own time. The faithful must wait patiently. This is an imperfect acrostic Psalm.
1-11 – Do not be envious of evildoers. Do not fret, be assured that God’s justice will come in the end, then evildoers will fade like grass and be no more, but the faithful, the meek, will inherit the land and delight themselves in peace. Psalm 37:1 is almost identical to Proverbs 24:19. Notice the commands in verses 3-11. Trust in the LORD, Do good, Dwell in the land, befriend faithfulness, Commit your way to the LORD, Trust in him, Be still before the LORD, Wait patiently for him, Refrain from anger, and Forsake wrath.
12-20 – The LORD thwarts the schemes of the wicked. The wicked think of all kinds evil schemes against the faithful, but the LORD sees to it that the wicked perish and that their evil schemes come to nothing. The LORD knows the days of the righteous; he is right there with them.
21-31 – Therefore, commit yourself to doing good. The singer reiterates that the wicked will be cutoff, but those blessed by the LORD will inherit the land. Only those faithful, blessed by the LORD, can do good because it is by the LORD that the steps of a man are established. One verse that means a lot to me is Psalm 37:25, I have been young, and now am old, yet I have not seen the righteous forsaken or his children begging bread. Verse 31 also, for one who has hidden God’s word in his heart, his steps do not slip.
32-40 – The LORD protects the righteous from the plots of the wicked. A common theme in the Psalms is that the faithful; are always under threat from the devices of the wicked, but they may trust in the LORD to preserve them. The singer then gives a final assurance that the LORD will not abandon the faithful to the power of the wicked, but will ensure that both the righteous and the wicked receive their proper regard in due time, most likely in the world to come.
