This dissertation analyzes Deut 31,9-13, recognizing the strategies used by YHWH to conduct his people by the knowledge of truth and the practice of justice. The Book of the King, that was written by Moses as it was ordered by YHWH, is a singular element. This pedagogic material was delivered to the Priests, Levi s sons and to the ancients. Josue, Moses s future successor, is, in this context, a highlighted figure. The book of the law attests the alliance established between YHWH, the one and only God, and Israel, the elected people. If the first point for the contact between YHWH and Israel had the purpose of freeing and saving them from the slavery of Egpty; The second point indicates the pedagogic project of YHWH: wishes israel s people to be free and faithful, and become a paradigm for other nations, that is, he wants his saving plan to extend to all humanity. The promised land, gift and heritage, after the time of the desert there will be the great trial. Moses was chosen for the sublime mission of conducting the people. The word of order is: obedience; that must translate into love and fidelity to the alliance s God. By being obedient, his people will reach their blessings, otherwise, by being disobedient, they will attract curses, lose their lands and will be exiled. The approach of the Dt 31,9-13 was done following the Historical and critical method, however, the research through the synchronic approach applied in the commentary, also sought to understand, through the logic, the pedagogy of YHWH in front of the people that he elected as private property. A history with its highs and lows, marked by the fidelity of YHWH and infidelities of his people always called to live according to the alliance. Blessings and curses mark this history that keeps going and being written in the mind and heart of each believer. The concern with the development of the future generations is the fundamental fact, in order for the obedience of the faith to be the way of conformation with the saving will of YHWH.
