Preparing this morning to go to shul for Simchas Torah in Beitar Illit, there were a few muffled explosions, but I didn’t think much of it – one often hears such noises. But then, the air raid siren went off, and I began to worry as I entered the mamad (secure room). Eventually, I decided to venture out to shul. The non-Jewish security guard said that there had been a terror incident in Beit Shemesh (information that turned out to be false). But then, in the middle of Shacharis, the siren went off again – and we all crowded into the shul bomb shelter. We ventured out, skipped hakafos, said Yizkor, and then another siren. And another. Eight sirens in all, over the next few hours. I never made it to hakafos, although things seemed to settle down towards the afternoon. Waiting to hear the news at the end of Yom Tov, my mind wandered to another Simchas Torah, 21 years ago.
