Psalm 71v15-18

¹⁵ My mouth will tell about your righteousness,
    and of your salvation all day,
    though I don’t know its full measure.
¹⁶ I will come with the mighty acts of the Lord Yahweh.
    I will make mention of your righteousness, even of yours alone.
¹⁷ God, you have taught me from my youth.
    Until now, I have declared your wondrous works.
¹⁸ Yes, even when I am old and gray-haired, God, don’t forsake me,
    until I have declared your strength to the next generation,
    your might to everyone who is to come.
