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.  [restrict] He strengthens those who are weak and tired.  Even those who are young grow weak; young men can fall exhausted.  But those who trust in the LORD for help will 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. Isaiah 40.28-31, TEV [/restrict
