Giving Thanks
55) Three tenths are three times Yod, Yod, Yod found in HaVaYaH with a filling of SAG. They are the subsequent Mitzva—to give thanks. The thanks is twenty tenths, which divide into ten tenths for the leaven and ten tenths for the Matza. Thirty Matzot [plural of Matza] are made of the ten of Matza, and ten Hallahs are made of the ten of leaven. This is the “Unleavened cakes of fine flour mixed with oil, or unleavened wafers spread with oil.”
Of the ten tenths—which are the ten letters of HaVaYaH with a filling of SAG, which are Yod–Hey–Vav–Hey—thirty Matzot are made, which are Yod, Yod, Yod in HaVaYaH de SAG, which is thirty in Gematria. This is three tenths, the name HaVaYaH with a filling of SAG, once to the right, Hesed, and once to the left, Gevura, and once in the middle, Rachamim [mercy] from each side, to the right and to the left, since the middle line includes right and left.
56) Sometimes the Yod, Malchut, is on the right, and it was written that there are no less than ten Malchuts in her. Sometimes the Yod, Malchut, is on the left, as it is written that there are no less than ten Shofars [horns] in her, since then she is called “a Shofar,” like Ima, which is on the left. And sometimes the Yod, Malchut, is in the middle, between right and left. At that time she is called “memory,” after ZA, who is the middle line, as it was written that there are no less than ten memories in her.
