28 Have thou not known? Have thou not heard? The everlasting God, LORD, the Creator of the ends of the earth, faints not, nor is weary. There is no searching of his understanding.

29 He gives power to the faint. And to him who has no might he increases strength.

30 Even the youths shall faint and be weary, and the young men shall utterly fall.

31 But those who wait for LORD shall renew their strength. They shall mount up with wings as eagles. They shall run, and not be weary. They shall walk, and not faint.
