28 Do you not know? Have you not heard? The Everlasting God, the Lord, the Creator of the ends of the earth does not become weary or tired. His understanding is inscrutable
29 He gives strength to the weary, And to him who lacks might He increases power.
30 Though youths grow weary and tired, and virgorous young men stumble badly,
31 Yet those who wait for the Lord will gain new strength; they will mount up with wings like eagles, the will run and not get tired they will walk and not become weary.
