Purim in walled cities (meaning, practically, in Jerusalem) occurs on the day after it does outside of them. This means that when Purim falls on a Friday, it falls on Shabbat in Jerusalem. This unique occurrence is called Purim Meshulash, “Threefold Purim,” because the practices for the day are divided into three. The megillah is read and gifts are given to the poor on Friday, the Torah reading is on Shabbat, and the festive meal and gifts to friends on Sunday. Since this practice of Shabbat Purim is unique to Jerusalem, and for much of Ashkenazi poetic history the Jewish community in Jerusalem was negligible, there are very few liturgical texts designed for Shabbat Purim Meshulash. This is, in the author’s opinion, a shame, because all the other special shabbatot surrounding it have a plethora of special piyyuṭim to insert into their cycles. This cycle of a shiv’ata (sevenfold piyyut) and an eloheikhem (Qedushah insertion) is meant to fill that void. . . .
