The King Messias will have to take the complement the Alliance. The King at this moment of the History of People of God is the Mediator between the People and the God of the Alliance becomes thus the Monarchy an institution of Salvation and object of hope (14). In the period of the prophets, the messianic expectations with respect of King Messias if had developed at 3 distinct moments, according to time and the perspective of each Project. At a first moment (the People of divided God in Kingdom of the north and the south) the prophets denounce with a hard and dramatical language the removal of the people of God of the observance of the Alliance. God is not plus an alive and present personage in history. The people starts to have a false conception of hope in the future, and the experiences of the past more are not happened again, God do not intervine at the decisive moments. The idea of ' is born; ' Day of Iahweh' ' , in which God would intervine, judge the enemies and in a way again ' ' almost mgico' ' he would assure the largeness of the People of God front to the other peoples. Ams is the prophet who it demystifies without no mercy this conception of future. Am 5,18ss: ' ' There of that they desire the day of Iahweh! So that it will serve you the day of Iahweh? ' '. Ams proclaims not a mundane expectation intra of nationalistic projects (victory against the enemies), but a hope in direction the God, the observance of its alliance and the private future Israel in a Universal vision. This subject of ' ' day of Iahweh' ' , in Ams and other prophets if they present in cosmic dimensions, can be considered as eschatological and that they supply elements to demonstrate the development of the Biblical Escatologia.
