Don’t you know? Haven’t you heard? The LORD is the everlasting God; he created the entire world. He never grows tired or weary. No one understands his thoughts. 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.
