Renting Out a Catering Hall For Mixed Dancing

So we're going

to get to that question, if there's another hole.

So we do need to define the parameters of Lifnei Iver and Messiah.

So we have a Gemara Vaydezara, Gemara Vaydezara, and it says in a few other places, similar sugyas, it says if you give an animal to an Akim, someone who may worship the animal, it's Lifnei Iver for a Vaydezara if he doesn't already have an animal.

Okay? So the gemara says, wait, so you're telling me that if he can do, if he already has it, meaning he can do the isser without you, it's not an isser of l'fneiver? Aye, we have a b'risah that says that passing a cup to a nazir, or aivar m'rachai to a guy, is l'fneiver.

And l'cheira, if you don't pass the cup to the nazir, he could go get it himself.

So we see the fact that you are able to do the isser without the person passing the cup, it's still a problem of Neva.

That's the more it's Kasha, that's the more it gives.

The answer that shapes the entire Suggia, which is the case of the Nazar, is tre iver den ari.

It's two sides of the river.

In other words, if you don't pass the cup to the Nazar, he will not, in fact, be able to access the cup.

Right? So it's very clear from the Gemara that the Isser, the Arayis of Lefebvre, only applies when it's tre iver den ari, which means that if not for you, he cannot, he would not be able to do the Isser.

So, says Rav Moshe, as Shalemi pointed out, in a large city such as London, yeah, obviously you're not the only game in town.

Which again, I don't know if it's so obvious, right? We know with the large city of Los Angeles, it still doesn't have a wedding catering hall, right? In 2026.

So I don't know if in 1958, how many wedding catering halls there were in London.

But Al-Qa'pan Rav Moshe says, in a large city such as London, you're obviously not the only game in town, and the couple can easily obtain another hall.

So there is no Yisr Doi Reis of Lifnei Yibre Yisrit HaMashiach.

That settles that.

What we do have to discuss, however, is the Yisr Derabonon of Messiah L'dayi Avira.

Because many Mishoinim, including Tosis, the Rosh, and the Ran, among others, say that even where you have Chadev Yerdenar, meaning that it's one side of the river and the guy does not need you to perform the Yisr, there is still an Yisr Derabonon of Messiah L'dayi Avira.

Because we know there's a chiev to be mafresh, especially when it comes to what Gemara says.

It's a big discussion.

It's not like us.

Let's just assume that we have a duty to stop a cotton from being mafresh.

So that means that leads to the fact that we also shouldn't be causing people or helping, assisting people to do aveiras.
