28 Hast thou not known? hast thou not heard? The everlasting God, Jehovah, the Creator of the ends of the earth, fainteth not, neither is weary; there is no searching of his understanding. 29 He giveth power to the faint; and to him that hath no might he increaseth strength. 30 Even the youths shall faint and be weary, and the young men shall utterly fall: 31 but they that wait for Jehovah 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.
