741. Come and see: In Egypt THAT "WILD BEAST OF THE REED GRASS" rules, and a number of different types of regime issue from it. And they all are in the secret of chametz. Since the Holy One, blessed be He, broke it, He removed the chametz (lit. 'leavened bread') and introduced matzah (lit. 'unleavened bread'). What did He use TO BREAK IT? With the smallest and thinnest thread, He broke the letter Chet of chametz (Chet Mem Tzadi). Thus it is called "the wild beasts of the reed grass" because it is as easy to break as is reed. With what was it broken? It was with a thread small as a hair that He broke the Chet and removed it from its former state and it became matzah. Therefore it is written: "Rebuke the wild beast of the reed grass," for the Holy One, blessed be He, rebuked it, and the Chet of chametz was broken and became a Hei.
