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