Psalms 71:15-18

15My mouth will tell about your righteousness and your salvation all day long, though I cannot sum them up.

16I come because of the mighty acts of the Lord God; I will proclaim your righteousness, yours alone.

17God, you have taught me from my youth, and I still proclaim your wondrous works.

18Even 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.
