Jamieson, Fausset and Brown on Psalms 37:1-2

PSALM 37

Psa 37:1-40. A composed and uniform trust in God and a constant course of integrity are urged in view of the blessedness of the truly pious, contrasted in various aspects with the final ruin of the wicked. Thus the wisdom and justice of God's providence are vindicated, and its seeming inequalities, which excite the cavils of the wicked and the distrust of the pious, are explained. David's personal history abundantly illustrates the Psalm.

1-2. The general sentiment of the whole Psalm is expressed. The righteous need not be vexed by the prosperity of the wicked; for it is transient, and their destiny undesirable.
