Psalm 73:13-17

13Surely in vain I have kept my heart pure and have washed my hands in innocence.

14All day long I have been afflicted, and every morning brings new punishments.

15If I had spoken out like that, I would have betrayed your children.

16When I tried to understand all this, it troubled me deeply

17till I entered the sanctuary of God; then I understood their final destiny.
