Isaiah 40:26-31

Lift up your eyes on high, and see who hath created these, that bringeth out their host by number; he calleth them all by name; by the greatness of his might, and for that he is strong in power, not one is lacking. Why sayest thou, O Jacob, and speakest, O Israel, My way is hid from Jehovah, and the justice due to me is passed away from my God? 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. He giveth power to the faint; and to him that hath no might he increaseth strength. Even the youths shall faint and be weary, and the young men shall utterly fall: 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.
