107. Come and see that when Jacob wished his sons to be blessed in the name of the Faith, it is written, "All these are the twelve tribes of Yisrael: and this (Heb. zot fem.) IS THAT WHICH THEIR FATHER SPOKE TO THEM" (Beresheet 49:28). TWELVE AND ZOT are thirteen, since the Shechinah, CALLED ZOT, participated with them and the blessings were fulfilled. This is the meaning of the verse, "Every one according to his blessing he blessed them" (Ibid.). What is meant by "according to his blessing?" MEANING according to the resemblance to that which is above, THE THIRTEEN ATTRIBUTES OF MERCY, NAMELY according to the blessing of each attribute.
382. Rabbi Yitzchak said, "There the tribes used to go, the tribes of Yah" (Ibid. 4). Who are the tribes? HE ANSWERS: These are the twelve boundaries that spread from that large and strong tree, BEING ZEIR ANPIN, BEING THE SECRET OF FOUR SFIROT - CHESED, GVURAH, TIFERET AND MALCHUT. EACH HAS THREE COLUMNS WHICH ARE TWELVE BOUNDARIES. FROM ZEIR ANPIN, THEY ARE DRAWN TO MALCHUT, WHERE THEY ARE CALLED BY THE NAME OF TWELVE TRIBES that HE inherited from Aba and Ima. This is what is written, "The tribes of Yah," MEANING from the good testimony that the holy son gives, as it is written, "The tribes of Yah, an appointed practice (lit. 'testimony') for Yisrael," AS THE TWELVE BOUNDARIES ARE THE SECRET OF THE TESTIMONY, MEANING THE ILLUMINATION OF EDEN (CHOCHMAH). These are the deep rivers flowing from Yah (Yud Hei), WHICH ARE ABA AND IMA. It is all for the purpose "to give thanks to the name of Hashem" (Ibid. 4). THEREFORE, "for there are set thrones of Judgment, the thrones of the house of David" (Ibid. 5), in order to bequeath the Holy Kingdom to him and his sons for generations. This is the poem recited by David concerning the holy, supernal kingdom.
