Psalms 73:12-17

This is what the wicked are like— always free of care, they go on amassing wealth. Surely in vain I have kept my heart pure and have washed my hands in innocence. All day long I have been afflicted, and every morning brings new punishments. If I had spoken out like that, I would have betrayed your children. When I tried to understand all this, it troubled me deeply till I entered the sanctuary of God; then I understood their final destiny.
