Psalm 71:17-19

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. Thy righteousness also, O God, is very high, who hast done great things: O God, who is like unto thee!
