Psalms 71:15-18

15My mouth shall show forth thy righteousness and thy salvation all the day; for I know not their numbers. 16I will go in the strength of the Lord GOD: I will make mention of thy righteousness, even of thine only. 17O God, thou hast taught me from my youth: and to this day have I declared thy wondrous works. 18Now also when I am old and grayheaded, O God, forsake me not; until I have shown thy strength to this generation, and thy power to every one that is to come.12
