Isaiah 40:29-31

International Standard Version

²⁹ He’s the^[a] one who gives might to the faint,
    renewing strength for the powerless.
³⁰ Even boys grow tired and weary,
    and young men collapse and fall,
³¹ but those who keep waiting for the Lord will renew their strength.
    Then^[b] they’ll soar on wings like eagles;
they’ll run and not grow weary;
    they’ll walk and not grow tired.”
