Psalm 71:14–18

14   But I will hope continually
    and will praise you yet more and more.
15   My mouth will tell of your righteous acts,
    of your deeds of salvation all the day,
    for their number is past my knowledge.
16   With the mighty deeds of the Lord GOD I will come;
    I will remind them of your righteousness, yours alone.
17   O God, from my youth you have taught me,
    and I still proclaim your wondrous deeds.
18   So even to old age and gray hairs,
    O God, do not forsake me,
  until I proclaim your might to another generation,
    your power to all those to come.

Psalm 92:12–15

12   The righteous flourish like the palm tree
    and grow like a cedar in Lebanon.
13   They are planted in the house of the LORD;
    they flourish in the courts of our God.
14   They still bear fruit in old age;
    they are ever full of sap and green,
15   to declare that the LORD is upright;
    he is my rock, and there is no unrighteousness in him.
