A few bonus verses to add to 29.
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 they who wait for the Lord shall renew their strength; they shall mount up with wings like eagles;
they shall run and not be weary; they shall walk and not faint.
— Isaiah 40:29-32 (ESV)
