Eruvin — Daf 83b

כדי עיסותיכם וכמה עיסותיכם כדי עיסת המדבר וכמה עיסת המדבר

דכתיב (שמות טז, לו) והעומר עשירית האיפה הוא מכאן אמרו ז' רבעים קמח ועוד חייבת בחלה שהן ו' של ירושלמית שהן ה' של ציפורי

מכאן אמרו האוכל כמדה זו ה"ז בריא ומבורך יתר על כן רעבתן פחות מכאן מקולקל במעיו:

מתני׳ אנשי חצר ואנשי מרפסת ששכחו ולא עירבו כל שגבוה י' טפחים למרפסת פחות מכאן לחצר

חוליית הבור והסלע גבוהים עשרה טפחים למרפסת פחות מכאן לחצר

בד"א בסמוכה אבל במופלגת אפילו גבוה י' טפחים לחצר ואיזו היא סמוכה כל שאינה רחוקה ארבעה טפחים:

גמ׳ פשיטא לזה בפתח ולזה בפתח היינו חלון שבין שתי חצירות

לזה בזריקה ולזה בזריקה היינו כותל שבין ב' חצירות לזה בשלשול ולזה בשלשול היינו חריץ שבין ב' חצירות

לזה בפתח ולזה בזריקה היינו דרבה בר רב הונא אמר רב נחמן לזה בפתח ולזה בשלשול היינו דרב שיזבי אמר רב נחמן

לזה בשלשול ולזה בזריקה מאי

אמר רב שניהן אסורין ושמואל אמר נותנין אותו לזה שבשלשול שלזה תשמישו בנחת ולזה תשמישו בקשה וכל דבר שתשמישו לזה בנחת ולזה בקשה נותנים אותו לזה שתשמישו בנחת

תנן אנשי חצר ואנשי מרפסת ששכחו ולא עירבו כל שגבוה עשרה טפחים למרפסת פחות מכאן לחצר

קא סלקא דעתך מאי מרפסת

only if it is of the size of your dough;1 and what is the size of your dough? That of the dough of the wilderness. And what was the size of the dough of the wilderness? The one which is described: Now an omer is the tenth part of an ephah,2 from which it has been deduced3 [that dough made of a quantity of] flour of seven quarters [of a kab]4 and a fraction5 is liable to the dough-offering. This [quantity] is equal to six Jerusalem kab or five of the Sepphoris kab. From this it has been inferred6 that if a person consumes such a quantity of food7 he is sound in body and happy in mind.8 He who consumes a greater quantity is a glutton and he who consumes less suffers from bad digestion. MISHNAH. IF THE TENANTS OF A COURTYARD AND THE TENANTS ON ITS GALLERY9 FORGOT TO JOIN TOGETHER IN AN ‘ERUB,10 ANY LEVEL11 THAT IS HIGHER THAN TEN HANDBREADTHS BELONGS TO THE GALLERY,12 AND ANY LOWER LEVEL13 BELONGS TO THE COURTYARD.14 THE BANK AROUND A CISTERN, OR A ROCK, THAT IS TEN HANDBREADTHS HIGH BELONGS TO THE GALLERY12 BUT IF IT IS LOWER IT BELONGS TO THE COURTYARD.14 THIS, HOWEVER, APPLIES ONLY TO ONE THAT ADJOINS THE GALLERY, BUT ONE THAT IS REMOVED FROM IT, EVEN IF TEN HANDBREADTHS HIGH, BELONGS TO THE COURTYARD. AND WHAT OBJECT IS REGARDED AS ADJOINING? ONE THAT IS NOT FURTHER THAN FOUR HANDBREADTHS. GEMARA. It is quite obvious that if an area is easily accessible to two courtyards15 the law is exactly the same as in the case of a window between two courtyards;16 that if it17 is accessible to either courtyard only through thrusting the law is exactly the same as in the case of a wall between two courtyards;18 that if it19 is accessible to either only by means of lowering their things the law is identical with that of a trench between two courtyards;20 that if to the one it21 is easily accessible22 but to the other it is accessible only by means of thrusting, the law is identical with that which Rabbah son of R. Huna cited in the name of R. Nahman;20 that if it23 was easily accessible22 to the one while to the other it was accessible only by means of the lowering of objects, the law is identical with the one which R. Shezbi cited in the name of R. Nahman;20 what, however, is the law where it24 is accessible to one by means of lowering and to the other by means of thrusting?25 — Rab ruled: Both26 are forbidden [access], but Samuel ruled: Access to it is granted to the tenants27 that can use it by means of lowering things28 since to them its use is comparatively easy while to others its use is comparatively difficult, and any area the use of which is convenient to one and difficult to another is to be assigned to the one to whom its use is convenient. We learned: IF THE TENANTS OF A COURTYARD AND THE TENANTS ON ITS GALLERY FORGOT TO JOIN TOGETHER IN AN ‘ERUB ANY LEVEL THAT IS HIGHER THAN TEN HANDBREADTHS BELONGS TO THE GALLERY AND ANY LOWER LEVEL BELONGS TO THE COURTYARD. Assuming that by29 GALLERY kab = 3 X 6 X 4/10 log = 36/5 = 7 1/5 log = (since a log = 6 eggs) 7 log and 1 1/5 of an egg. VI, 16, 18ff). domain except through the courtyard into which they gained entry by means of a ladder. conveniently use that area, or is a distinction drawn between the respective degrees of inconvenience?
