256. Rabbi Chiya said that Abraham and Isaac each performed their marital duties with one wife on the side of holiness, BECAUSE HAGAR AND THE CONCUBINES WERE NOT OF HOLINESS. Abraham did so with Sarah, and Isaac with Rivkah. In comparison, Jacob had four wives, two each REPRESENTING THE HOLY AND THE NOT HOLY. LEAH AND RACHEL REPRESENTED HOLINESS, BILHAH AND ZILPHAH REPRESENTED THE NOT HOLY THAT HE CHANGED TO HOLY. Rabbi Shimon said that these matters have reached their proper place IN HOLINESS. EVEN HAGAR AND THE CONCUBINES WERE PART OF THE SECRET OF HOLINESS, AS RABBI SHIMON EXPLAINS THAT THE TWELVE WOMEN WERE BUT TWELVE ASPECTS OF THE NUKVA. For everything is done in the secret of holiness, and all is one secret; NAMELY, ALL OF THEM ARE INCLUDED WITHIN THE SECRET OF THE NUKVA OF ZEIR ANPIN ALONE.
