28 »Do you not know? Have you not heard? JEHOVAH IS THE EVERLASTING GOD, the Creator of the ends of the earth. He will not grow tired or weary, and no one can measure find out his understanding.
29 »He gives strength to those who grow tired and increases the strength of those who are weak.
30 Even young people grow tired and weary, and young men stumble and fall.
31 »Those who hope in Jehovah will renew their strength. They will soar on wings like eagles. They will run and not grow weary! They will walk and not be faint.«
