28 Don't you know? Haven't you heard?The Lord is the everlasting God;he created all the world.He never grows tired or weary.No one understands his thoughts.
29 He strengthens those who are weak and tired.
30 Even those who are young grow weak;young people can fall exhausted.
31 But those who trust in the Lord for helpwill find their strength renewed.They will rise on wings like eagles;they will run and not get weary;they will walk and not grow weak.
