4. Come and behold: the evil tongue of the Serpent, with which he spoke to the woman, brought death upon the man, the woman, and the whole world. Thus, it is written: "And their tongue a sharp sword" (Tehilim 57:5), referring to the evil tongue. Therefore, "be afraid of the sword," NAMELY the evil tongue. What does the following verse mean? "For wrath brings the punishments of the sword." This is "the sword of Hashem," for as we learned, the Holy One, blessed be He, has a sword with which He punishes the wicked, as it is written: "the sword of Hashem is filled with blood" (Yeshayah 34:6). It is also written: "My sword shall devour flesh," (Devarim 32:42) FOR THIS IS THE ASPECT OF JUDGMENT WITHIN MALCHUT. Therefore, "be afraid of the sword for wrath brings the punishments of the sword that you may know that there is judgment," WHICH MEANS that you know it has been so decreed, and THAT ANYONE who has a sword in his tongue - NAMELY, HE WHO SPEAKS WITH THE EVIL TONGUE - is punished with the sword that destroys all, FOR THIS IS MALCHUT FROM THE SIDE OF JUDGMENT. This is the meaning of: "This shall be the Torah of the leper;" THAT IS, MALCHUT FROM THE ASPECT OF JUDGMENT, WHICH IS CALLED 'THIS,' JUDGES THE LEPER FOR HIS EVIL TONGUE, BECAUSE PLAGUES COME FROM THE EVIL TONGUE.
