Psalms 71:14-18

But I will hope continually, And will praise You yet more and more. My mouth shall tell of Your righteousness And Your salvation all the day, For I do not know their limits. I will go in the strength of the Lord GOD; I will make mention of Your righteousness, of Yours only. O God, You have taught me from my youth; And to this day I declare Your wondrous works. Now also when I am old and grayheaded, O God, do not forsake me, Until I declare Your strength to this generation, Your power to everyone who is to come.
