A lot of jews saw the Oct 7 attack as divine punishment on the rave attendees.
Oct 7 was both the sabbath and Simchat Torah holiday. jews are supposed to go to their sinagogues, pray and dance about Hashem and the Torah.
Historically, jews have conducted false flag attacks on jewish citizens who don't observe these religious holidays.
This week, there is a sabbath and rosh hasana holiday. There are rumors and weird warnings made by rabbis these past two weeks. It should only affect jews though.
