Psalms 71:14-18

But I will hope continually and will praise you more and more. My mouth will tell about your righteousness and your salvation all day long, though I cannot sum them up. I come because of the mighty acts of the Lord GOD; I will proclaim your righteousness, yours alone. God, you have taught me from my youth, and I still proclaim your wondrous works. Even while I am old and gray, God, do not abandon me, while I proclaim your power to another generation, your strength to all who are to come.
