Isaiah 40:29-31 King James Version 29 He giveth power to the faint; and to them that have 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 upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.
