Psalm 71:16-18 KJV
I will go in the strength of the Lord GOD:
I will make mention of thy righteousness, even of thine only.
O God, thou hast taught me from my youth:
And hitherto have I declared thy wondrous works.
Now also when I am old and greyheaded, O God, forsake me not;
Until I have shewed thy strength unto this generation, and thy power to every one that is to come.
