Isaías 40

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.
