11 Because the sentence against an evil work is not executed speedily, therefore the heart of the sons of men is fully set in them to do evil. 12 Though a sinner does evil a hundred times, and his days are prolonged, yet I surely know that it will be well with those who fear God, who fear before Him. 13 But it will not be well with the wicked; nor will he prolong his days, which are as a shadow, because he does not fear before God.

Matthew Henry's Commentary on Ecclesiastes 8:11-13

Commentary on Ecclesiastes 8:9-13

(Read Ecclesiastes 8:9-13)

Solomon observed, that many a time one man rules over another to his hurt, and that prosperity hardens them in their wickedness. Sinners herein deceive themselves. Vengeance comes slowly, but it comes surely. A good man's days have some substance; he lives to a good purpose: a wicked man's days are all as a shadow, empty and worthless. Let us pray that we may view eternal things as near, real, and all-important.
