Jews around the world fast on the day after Rosh haShanah to commemorate the murder of Gedalyahu son of Aḥiqam, the officer appointed over Judah who sought to make peace and rebuild before being murdered by a religious extremist and officially bringing an end to the first commonwealth era. The tragedy of Gedalyahu is not just that he was assassinated, but that he was assassinated by a Jew who was using religion (specifically his claim to the line of David) as an excuse. This narrative bears striking similarities to the murder of Prime Minister Yitzḥaq Rabin on 12 Marḥeshvan 5756. On account of this, some Jews have taken it upon themselves to memorialize Rabin on Tzom Gedalyahu as well. This piyyut could be added to the seliḥot for Tzom Gedalyahu, or part of a new seliḥot service for 12 Marḥeshvan. . . .

There’s a lot of controversy over Yom haShoah as a date. One of the key issues is this: traditionally, the ways Jews mourn communal tragedies is through establishing a fast day. It’s forbidden to fast during the month of Nisan. It’s hard to pick any specific date to commemorate a tragedy as enormous as the Shoah, but one which seems appropriate to me would be 16 Marḥeshvan, the anniversary of Kristallnacht, the November Pogrom. This piyyut is a seliḥah for Kristallnacht, to be recited on 16 Marḥeshvan (or 15 Marḥeshvan on years like 5782 where the sixteenth falls on a Thursday). . . .
