Israel, why then do you complain that the Lord doesn't know your troubles or care if you suffer injustice?
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.
He strengthens those who are weak and tired.
Even those who are young grow weak; young people 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.
