HaKatan -“Health correctly referred to the Chazal that there are times, that once Hashem had allowed the mashchis to go forth, that his destruction was, to some extent, indiscriminate.”
I looked it up. It’s not so Pashut. The Sifsay Chachomim learns Rashi about the Mashchis is refering to the Mashchis of “night”, not of the Bechorim. (Night is a time of danger.) Ramban argues and learns the Mashchis is when a king goes out he has soldiers pushing people out of the way -so also Hashem went out in Egypt that night and anyone there would get pushed away (and possibly hurt) by his Malachim keeping e/o away.
But the Malbim learns this Possuk is dependant on the Maclokes of R’ Yoshea and R’ Yonasson that argue about what Oopasachti means. So acc. to R’ Yoshea the Mashchis wouldn’t go into a Jew’s house if a Mitzri was there because then he’d have to kill both and this is why a Jew should Not go outside on that night. And R’ Yonasson would argue and says the Mashchis did differentiate even in the same house. So this poster Jay can hold like this Shitta.
Still this would be in Mitzrayim where we had Nissim Geluyim happen to us -it’s unlikely Hashem would be Mavchen all the time, like during hurricaines because this would require a Neis Goluy.
Can you imagine how this would work out -one house would have flooding and the very next house -no flooding because it’s a Jew’s house. I don’t think nowadays anyone would hold Hashem would be Mavchen. We aren’t on the level to see Obvious Miracles!
