Isaiah 40:29-31

New Century Version

²⁹ He gives strength to those who are tired
    and more power to those who are weak.
³⁰ Even children become tired and need to rest,
    and young people trip and fall.
³¹ But the people who trust the Lord will become strong again.
They will rise up as an eagle in the sky;
    they will run and not need rest;
    they will walk and not become tired.
