578. AND THERE ARE TWO SORTS OF DUST, for the dust of Jacob, NAMELY HIS WAR, comes to teach merit about prayers, in a number of hosts of merits that are regiments and camps that gather with him to teach merit ABOUT THE PRAYER. And the dust from the level of Samael ascends in a number of camps of debt, teaching guilt ABOUT THE PRAYER. And this prayer of Arvit is called 'Jacob's Ladder', in which: "And behold the angels of Elohim ascending and descending on it" (Beresheet 28:12). These are THE PRAYERS that ascend WHEN THEY ARE liabilities, and merits descend in their place. FOR THE CAMPS OF THE TEACHERS OF MERIT OF JACOB OVERCAME THE CAMPS OF THE TEACHERS OF LIABILITY OF SAMAEL. And there are those that ascend as merits and liabilities descend in their stead. IN THIS CASE, THE CAMPS OF THE TEACHERS OF LIABILITY OF SAMAEL HAVE OVERCOME THE OTHERS, FOR THESE CAMPS humiliate them in a number of wars.

579. For they, WHO TEACH MERIT, are the defenders in the war of the Torah, until the war becomes audible to the great mountains, that is to Abraham, Isaac, and Jacob, as it is written: "Hear, O mountains, Hashem's controversy" (Michah 6:2). This is the controversy of prayer, the controversy of Torah, NAMELY THE CONTROVERSY OF THOSE WHO TEACH MERIT AND OF THOSE WHO TEACH LIABILITY OVER MAN'S STUDY OF TORAH AND PRAYER. And this war of Arvit continues until sunrise, for Rabban Gamliel determined it as until the rise of dawn, for Arvit may be said at any time during the night, but the sages erected a boundary around it AND DETERMINED IT as until midnight.

580. And because THE DUTY OF RECITING ARVIT IS UNTIL THE RISE OF DAWN, IT IS SAID: "and there wrestled a man with him until the breaking of the day" (Beresheet 32:24). What is meant by the dawn? It refers to Arvit, NAMELY THE SHECHINAH, whose limit is until the morning of Abraham, WHOSE TIME IS the fourth hour. "And Abraham rose up early in the morning" (Beresheet 22:3), namely at the beginning of the first hour at the end of the dawn, which is Netzach of Jacob, for there "To the chief musician (Heb. menatze'ach) upon the morning star" (Tehilim 22:1), to wreak vengeance on Samael for having touched Jacob's left thigh, which is Hod, of which it is said: "he has made me desolate and faint (Heb. davah - Dalet Vav Hei) all the day" (Eichah 1:13), WHERE THE LETTERS OF THE WORD DAVAH, REARRANGED, SPELL Hod. From the side of Hod, which is the fifth millenium, the Temple remained destroyed and barren.
