19. The following precept is to do to a witness convicted of false testimony as he thought to do to his brother. If the two false witnesses, Samael and the serpent, come to give false testimony against Yisrael that they confused between Vav and Zayin, NAMELY BETWEEN ZEIR ANPIN THAT IS CHESED, GVURAH, TIFERET, NETZACH, HOD, YESOD AND MALCHUT, THAT IS ZAYIN. MEANING, THEY HAVE SINNED AND DISTANCED BY THEIR SIN THE VAV, WHICH IS ZEIR ANPIN, FROM THE ZAYIN, WHICH IS MALCHUT, which are the letters of 'zu (Zayin Vav).' This is the meaning of, "This people which (Heb. zu) I have formed for Myself; they shall relate My praise" (Yeshayah 43:21), ALLUDING TO THE PEOPLE THAT UNITES THE ZAYIN WITH THE VAV.
20. The Vav will be united with the Zayin only by burning leavened bread, MEANING TO BURN THE KLIPOT THAT TAKE HOLD between the Vav and the Zayin - THAT IS, BETWEEN ZEIR ANPIN AND MALCHUT. Even though according to the laws of the Torah IT IS PERMISSIBLE TO EAT to the end of the sixth hour of the day, the sages have decreed that you may eat to the end of the fourth hour, hold it in suspense during the fifth hour, and burn it at the beginning of the sixth. The sages of the Mishnah deduced from the testimony regarding the hours of the disposition of leaven THAT ACCORDING TO THE LAWS OF THE TORAH THE TIME TO BURN IS PAST THE SIXTH HOUR - AT THE SEVENTH HOUR, to the testimonial regarding the examination of witnesses about one who has killed someone, WHICH ALSO REQUIRE SEVEN EXAMINATIONS, AS MENTIONED ABOVE, and everything is explained in the Mishnah. It shall be fulfilled REGARDING SAMAEL AND THE SERPENT, "in the thing wherein they dealt proudly" (Shemot 18:11), WHICH MEANS, IN THE SAME THING THE EGYPTIANS PLANNED TO PUNISH YISRAEL, THEY WERE PUNISHED. That is the meaning of: "then shall you do to him, as he had thought" (Devarim 19:19).
