Psalms 71:15-18

15My mouth will tell of your righteous deeds, of your saving acts all day long— though I know not how to relate them all. 16I will come and proclaim your mighty acts, Sovereign Lord; I will proclaim your righteous deeds, yours alone. 17Since my youth, God, you have taught me, and to this day I declare your marvelous deeds. 18Even when I am old and gray, do not forsake me, my God, till I declare your power to the next generation, your mighty acts to all who are to come.
