Psalms 71:18-20

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. 19Your righteousness, God, reaches to the heavens, you who have done great things. Who is like you, God? 20Though you have made me see troubles, many and bitter, you will restore my life again; from the depths of the earth you will again bring me up.
