Psalm 73:13-17

All in vain have I kept my heart clean and washed my hands in innocence. For all the day long I have been stricken and rebuked every morning. If I had said, “I will speak thus,” I would have betrayed the generation of your children. But when I thought how to understand this, it seemed to me a wearisome task, until I went into the sanctuary of God; then I discerned their end.
