Isaiah 40
27 Ref Why say you, Jacob, and speak, Israel, My way is hid from Yahweh, and the justice [due] to me is passed away from my God?
28 Ref Have you not known? have you not heard? The everlasting God, Yahweh, the Creator of the ends of the earth, doesn't faint, neither is weary; there is no searching of his understanding.
29 Ref He gives power to the faint; and to him who has no might he increases strength.
30 Ref Even the youths shall faint and be weary, and the young men shall utterly fall:
31 Ref but those who wait for Yahweh 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.
