An Overview of Maseches Eruvin

[Music] okay this series of shiurim is intended to be an introduction to messages irvine specifically for londe da fiomi now there's a notion out there that if you take a complex topic and you introduce it with a simplified introduction that the somehow the complex topic will just become simple and i wish it would work that way but it doesn't and of course we were the intention here is really to try to make messages irvin more accessible lambda da fiendi and we put a lot of thought into it then we really came to the conclusion that irvin is not so much it's not so much the complexity that's a challenge it's really the um abstract nature of all these topics now we don't live in a hutzer we don't have a mother we don't have these alleyways that were common in the times of ghazal even our seraphim our public domain does not function the way the public domain uh functioned in times of hazal so essentially the message irvine ends up being solutions to problems that we don't really have and using implements for example like a lefki now lefke is a board kyra beam now in practical halaq use these implements really fell out of practice so putting together the fact that the dome the domains and the are not really what we're used to and the implements are not what we're used to the topic becomes very abstract and it makes it very hard to retain very hard for us to properly visualize these things the purpose of this urine is to take the halakhah concepts you know organize them but then take it a step further and to create a share that will bridge the gap that will take these abstract concepts and bring them into practical application help us visualize them and make it a lot easier to understand the message that way also irvine is not just a conglomeration of halal concepts it's also a thought process you have to yeah it's a thought process the unique thought process you look at a domain and you try to figure out what this domain what what what it takes to to properly enclose it what it takes to make this interesting and we're trying to we'll try to introduce not just the concepts but the thought process of ms after saying and using carefully um picked um case studies to try to bring this down to a more practical level and to give us the thought process and that again will be a very big tool to help us understand the message now the message is really comprised of four primary topics and we're going to try to commit a full share to each of these four topics the first of these topics are actually the first three really relate to one central theme and the shabbos um we discussed it as one of the 39 malachis and that relates to the fact that you're not allowed to carry between a risha a public domain and it was just that you offered a private domain now it's just a rabbit with something very specific as the gemara defines it as a sratio platygodaila a sratya is somewhat aware of street platya a street a main place that's meant for hilo harabin for public traffic um godila which is a large public street or a platy like more like a plaza something that's meant for congregating but also a pub very public domain with a few other debt of of prerequisites tessa and amma not having a roof um perhaps it requires six hundred thousand people so that's what's just haram and it's an extreme public domain and then on the other end we have versus a private domain and um carrying from them all the way to the other end of the extreme that is a russia that's us um and on a derisive level the entire in between the entire cameras and between her surroundings has no issue right so it does not relate to a karmalist so and under isolation there's no point in trying to create a resource there's no benefit of being having ursus however on a durable level their abundance say we're not allowed carrying unless we're not going to allow you to carry unless the area is a complete and total vicious and they get it went even beyond that and that's what the first three topics of ervin really relate to such as it's all going to relate to creating a perfect resource even on their bottom level now the first of these three mushrits it has to be surrounded with proper valid partitions um you can have offenses of tenth falcon tall that's a perfect complete machita and now there are these other um implements these implements uh supplement if you have uh you already have three walls so on the fourth side you could put a kyrie a board a beam and this this is something that's discussed what it does it take to create the sum total of a correct enclosure which is the first step in creating that's the second thing that relates to creating this is and the negative we have to be able to create a visual we have to make sure that the area doesn't begin by being arrested if the area begins as a complete rishis arab and a complete public domain so then the typical implements that are used to create irish will not will not be sufficient you're going to have to do something else maybe you'll make thousands to make doors to prevent the helicopter to prevent the public traffic to from flowing freely so that's something else that we have to know we have to know where is there just arabim and how that's going to affect the ability to make irish the third and that takes the allah which is one step further after you enclose it and at the right level of course it's a completely said wait there's something else that might be a concern here it maybe it's originally up and it's properly enclosed but does it give the full impression of being let's say i'm carrying something from my house it's a private domain and i'm going to be carrying from my house to a sheared yard so now on a certain level that may come across as i'm carrying from mauritius in my private house it's only mine to a yard okay granted it's enclosed and it's really rich but it doesn't have the same impression it's shared with other people perhaps that could be confused with the fact that i to within i'm carrying from a more private to a lesser private domain so the fazal said no that's also not good and you somehow have to make this yard using an area of caceres and a food item which will be discussed in the later practicum of south deserving you have to do something to create the impression that no this is not a shared yard this is a private yard and then you could carry from your house to the yard and various other halaquahs come into play so that's the law of kazeras the fourth topic relates to now is really a different concept but it shares the same word erev it also used the word eruph and er of the relates to a different type of isr there is an issue that once somebody is he's situated in a city the beginning of shabbos so that becomes his malcolm dear that's where he's going to be for shabbos now fro once that that gets established he's only allowed to walk 2 000 amis in each direction from his city where he is situated in the beginning of shabbos suppose somebody wants to be able to go 4 000 atmos so what does he what could he do right so he is down by his trum of 2000 amis so there's something called an erev which allows him to go a bit further you put the air of the let's say at the end of 2000 atmos and now he could go 2000 amis further he could walk in further in that direction so that's the fourth topic that's mr hashem going to be addressed in a fourth year are dedicated to the survey of truman you
