Jewish Mysticism
In the future, which is the end of days, in the sixth day, which is the sixth millennium, the Messiah will come. … Even though the portion of the Community of Israel is on the fourth day, she is alluded to on the sixth day in order to be proximate to her husband who is called Saddiq, the day of Sabbath, in order to prepare the table for him. Thus it is written, “For the Lord has created something new on earth, a woman shall encircle a man” (Jer. 31-21). This is in the time of the Messiah, which is the sixth day, and thus it is written “And there was evening and there was morning, the sixth day” (Gen. 1-31). Why [does Scripture] add here a [letter] he’ [in the word] ha-shishi in contrast to all the other days? In every place the he’ refers to the Community of Israel, which comes to unite with her husband, the day of Sabbath. When her husband comes to her, he raises her from the dust.
