Zaburi 71:18

Ee Mungu, usiniache, hata niwapo mzee wa mvi, mpaka nitangaze uwezo wako kwa kizazi kijacho, nguvu zako kwa wote watakaokuja baadaye.

Now also when I am old and grayheaded, O God, forsake me not; until I have shewed thy strength unto this generation, and thy power to every one that is to come.
