29 He gives power to the faint,

and to him who has no might he increases strength.

30 Even youths shall faint and be weary,

and young men shall fall exhausted;

31 but *Ps. 103:5they who wait for the Lord shall renew their strength;

they shall mount up with wings *[Ex. 19:4]like eagles;

they shall run and not be weary;

they shall walk and not faint.
