Psalms 73:13-17

Did I keep my heart pure for nothing? Did I keep myself innocent for no reason? I get nothing but trouble all day long; every morning brings me pain. If I had really spoken this way to others, I would have been a traitor to your people. So I tried to understand why the wicked prosper. But what a difficult task it is! Then I went into your sanctuary, O God, and I finally understood the destiny of the wicked.
