  After discussing the prophecy of Moses, Albo takes up the topic of the divine Torah that Moses gave to the people of Israel. He treats a number of aspects of this issue, such as the classification of the mitzvot (commandments), the status of the Ten Commandments, and the importance of the Oral Law. Yet apparently, the thrust of his efforts is directed toward establishing the idea of the eternity of the Torah, apparently in response to the Jewish-Christian polemic on this topic. Remaining faithful to his dogmatic method, Albo argues that in Mosaic law, and in divine law in general, changes in the details of the commandments may take place, but their fundamental principles cannot change (treatise 3, chapters 13–22).
