as we've established
six houses together form one halachic
city for truman
and it's all considered like four amis
and the two thousand armist the ones
entitled to walk in each direction of
shabbos
to not begin until it leaves city
now sometimes we can merge together two
cities and form one
super city how do we do that so the
first example is the before submission
is that after you leave the city before
you even begin
the two thousand almost of tom shamus
you're entitled to karafe
we make a kaffir around the city well
there's a kafir min
it means we give an area of 70 and
two-thirds amis
or in our language 125 feet around the
city
that's considered an extension of the
city and only after that
do you begin the 2000 amis of trimshabus
now let's say you have two cities that
are near each other
so much so that the car fifa's of the
two cities overlap
that means the last house in city a is
less than 250 feet
from the first house in city b so the
cara fifa is the extensions of the two
cities overlap
then the mishnah says that the two
cities are considered like one
and the two thousand almost who starts
off in city a
do not begin until he leaves city b and
the 2000 amis
of somebody who's starting in city b do
not begin
until he's made out from the other end
of city a so you have a tremendous ear a
super city
that you get before you even start your
2000 almost of tromshabas
and now we could take this even a step
farther and create
a super duper city because
is that before you start your 2000 amis
of kamshabas when you leave a city
you square off the city we've mentioned
this in terms of with houses and fenced
in areas that if they're not a perfect
square
you square it off tempe is the scheife
shabbos like the gemara says in irvine
daffodil
you square it off and only after that do
you begin the
of 2000 shabbas so here also when you
have the alaska city
you don't just start your 2000 amis when
you exit the city at one end
rather we square off the city so if you
have a round city or say that squiggly
on any side
most of our cities are like that you
square them off now in the olden days
and times of the gamora
some cities had to be squared off and
some of them were naturally square
because they had walls around the city
so very often the wall was built as a
straight line
and the wall of the city was like a
fence similarly nowadays if you have a
city that has an arab around it it's
possible that the area of on
let's just say the eastern side of the
city is one straight line
so then there's no squaring off to do on
that side because we have a natural
straight line at the edge of the city
but in most cases most alaska cities are
jagged or rounded on all four sides
so before we start the two thousand arms
of trom shabbas
we first have to square it off we make a
ribua
we square off the cities so one could
refer to the braisa and afternoon ham
and alvin irvin
and see over there many details in many
alakas in terms of squaring all cities
now let's say the squaring off of one
city which is now an extension of that
city
juts into another city or juts into the
squaring off of a different city
so the acceptable sack of most paiskim
khaznish and others
is that these two cities are now
considered one similarly to what we
established a few minutes ago we
established previously
to have two car fifa's overlap if the
two cities come within 250 feet of each
other
they are now considered one super city
the same applies in terms of the ribua
the squared off area of the city if the
squared off area of city a
johnson the city b or just jots into the
square of area of city b
now city a and b are considered one big
city
and one does not start their 2000 amis
of trump shabbos
until they have left city a and b until
they have left
the super squaring off of the whole
situation of halachic sydney a
and alaka city b now when we talk about
squaring off cities
so there's one very important thing to
know the gemara says
an irvine now if you have an ear i see
it caches a city that's shaped like a
rainbow
most people know that caches is a
rainbow if you have a city that's shaped
like a rainbow
or we could say like the leather s so if
the from the two
ends of the rainbow if the two ends of
the hess is more than four thousand arms
more than seven thousand and eighty feet
so then we cannot be mirabea we cannot
square off on this side it's nearer
geste
uras it appears like two separate cities
because the two extents of the city the
two ends of the sea are so far from each
other
without houses in between filling it up
so in such a case we do not get aribua
we do not get the square off so we do
not get the square off and therefore
somebody who leaves
the city starting from somewhere in the
middle of the caches in the middle of
the rainbow
and he starts walking out his two
thousand elements for trump shabbos
are gonna begin pretty much right away
similarly also if another city juts into
the
this area this seven thousand foot area
between the two ends of the city
the two cities are not going to become
unlockedly attached or not become one
because there's no reboot given there's
no squaring off given
to the caches so if the distance between
the two russia caches the two heads of
the rainbow
is less than seven thousand feet then we
do square it off we do close that up
in fact many places can feel that that's
even stronger than rebuild we fill it in
almost as if it's part of the city we
imagine like the gemara says kill the
molly baltimore
as if it's filled up with houses and
courtyards however if the distance
between the two heads of the city
it's more than 4 000 more than 7080 feet
then there's no squaring off done
at all similarly if you have an ira
seeker gam
gam is a greek letter it's an example of
a shape of a city
it's something akin to a backwards
capital l so you have a c that's shaped
like this like an l
if between the two ends of the gum
between
the top of the gum and the foot of the
gum the distance is more on the diagonal
is more than four thousand almost more
than seven thousand eighty feet
we do not square off the gum if the
distance is less than those seven
thousand eighty feet we do square off
the gum
and now becomes like a triangle and now
we further square it off by creating a
mirror image to make it into a full
proper square
like we always like to make our halachic
cities into squares
at rectangles however if the distance
between the two ends
is more than four thousand almost more
than seven thousand and eighty feet
we cannot square it off and therefore
somebody who walks out this gum on
shabbos he's walking through the middle
of the gamut two thousand armies for tom
shabas
already begin and if there's another
city that juts into the
this area between the two ends of the
gum that
does not make that other city connected
to our city which is shaped like a gum
like a backwards l
or rather they're each considered like
separate cities in regards
to trim shabbos
