Ki Tetze: Chapter 13
The Leviathan

Rav Hamnuna Saba tells Moses that he is the Leviathan of the sea of the Torah, the master of all fishes. The sages of the Mishnah have stated that the Torah is maintained only by those who are willing to die for it, and part of the meaning here is that death is poverty. In response to Moses' query about the Leviathan, Rabbi Shimon answers that is it he whose grade is the Central Pillar, a righteous man who grows in the sea of supernal Ima where God is unified through the Sh'ma and the prayer 'Blessed be....' Moses says that the world is supported by that Leviathan.
