Isaiah 40:29-31

Authorized (King James) Version

²⁹ He giveth power to the faint;
and to them that have no might he increaseth strength.
³⁰ Even the youths shall faint and be weary,
and the young men shall utterly fall:
³¹ but they that wait upon the Lord shall renew their strength;
they shall mount up with wings as eagles;
they shall run, and not be weary;
and they shall walk, and not faint.
