In the preface to his book Emek Hamelech Rabbi Naftali Bacharach lists his ten books, noting that the first is Emek Hamelech , and the second is Gan ha-Melekh , his commentary on the Zohar printed here for the first time. Bacharach's style in Emek Hamelech is similar to his style in Gan Hamelech , however, while Emek Hamelech was written according to the order of Emanation, Gan Hamelech was written as a commentary to the Zohar. In general, the Kabbalistic writing of Bacharach is characterized by the fact that it is full of messianic tension, and unlike most descriptions of the Emanation in Lurianic Kabbalah that we are familiar with, Bacharach also describes the first stages of the Emanation in Messianic terms.

The characters of the Yanuka (the Zoharic Wunderkind) and the Sava (the wise old man), appear in various Zoharic stories, revealing themselves to the sages of the Zohar (Rabbi Shimon Bar Yohai and his disciples). These two figures are among the most meaningful and complex mythical figures in Zoharic literature. The main argument in this work is that the Sava and Yanuka characters are portrayed as the embodiment of God and his Son (and the Messiah). This book is the first attempt to grasp the full extent and depth of these mythical figures and the close ties that exist between them. At the same time, the book reveals an important chapter in the history of Jewish myth and contributes to the understanding of the messianic consciousness that characterizes the stories of the Sava and Yanuka in the Zohar and exposes their hidden and polemical ties with Christianity.
