Psalms 37:37

37Observe the perfect man David exhorts the faithful diligently to consider every instance they may meet with of the grace of God, as well as of his judgment; but he teaches, at the same time, that it is in vain for any to sit in judgment upon the first aspect of things. When men do not wait patiently and quietly the time which God has appointed in his good pleasure, it often happens that faith is extinguished, and trust in the promises of God, at the same time, perishes with it. This is the reason why David exhorts us to observe and consider, for when our minds are preoccupied by the temptation which is once presented to our view, hasty judgment is then the cause of our being deceived. But if a man extend his view, as if it were from a watch-tower, to a great distance, he will find that it has been said with truth, that the end of the reprobate and the end of the righteous respectively are at length very different. This clause, with respect to the end of these two classes of men, seems to be added by way of caution, that we may learn to suspend our judgment, if God should not immediately accomplish what he has spoken. If we should become impatient in our desires, let us moderate our minds by the reflection, that the end is not yet come, and that it behoves us to give God time to restore to order the confused state of things. Some explain the word אחרית, acharith, which we have rendered the end of the wicked, of their posterity. This, however, is incorrect. David refers only to the difference which subsists between them and the righteous in the end; for God, after he has severely tried his servants, and exercised their patience, in the end converts their adversity into a blessing, while he turns the mirth of the ungodly into mourning.
