Psalm 71:18 Even when I am old and gray, do not forsake me, O God, till I declare your power to the next generation, your might to all who are to come.
Psalm 92:12-15 The righteous will flourish like a palm tree, they will grow like a cedar of Lebanon; planted in the house of the LORD, they will flourish in the courts of our God. They will still bear fruit in old age, they will stay fresh and green, proclaiming, “The LORD is upright; he is my Rock, and there is no wickedness in him.”
