Isaiah 40
27 Ref 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?
28 Ref 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 Ref He giveth power to the faint; and to him that hath no might he increaseth strength.
30 Ref Even the youths shall faint and be weary, and the young men shall utterly fall:
31 Ref 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.
