Psalm 71:9-18

Cast me not off nor send me away in the time of old age; forsake me not when my strength is spent and my powers fail. For my enemies talk against me; those who watch for my life consult together, Saying, God has forsaken him; pursue and persecute and take him, for there is none to deliver him. O God, be not far from me! O my God, make haste to help me! Let them be put to shame and consumed who are adversaries to my life; let them be covered with reproach, scorn, and dishonor who seek and require my hurt. But I will hope continually, and will praise You yet more and more. My mouth shall tell of Your righteous acts and of Your deeds of salvation all the day, for their number is more than I know. I will come in the strength and with the mighty acts of the Lord God; I will mention and praise Your righteousness, even Yours alone. O God, You have taught me from my youth, and hitherto have I declared Your wondrous works. Yes, even when I am old and gray-headed, O God, forsake me not, [but keep me alive] until I have declared Your mighty strength to [this] generation, and Your might and power to all that are to come.
