עירובין י׳:ח׳ - י׳:ט׳

המיסך – that its branches hang over downwards from all of its sides around.

מטלטלין תחתיו – for since its branches are not three handbreadths or higher from the ground, they are like the legal fiction of considering separated parts as united and they are seen as partitions. Therefore, it is permitted to carry underneath it, but nevertheless, it is necessary to fill the airspace that is between the branches and the land with straw, stubble and similar things, and to tie up the branches so that the wind doesn’t move them for a partition that is unable to withstand a wind that is present is not a partition. But we don’t carry in it other than in a field requiring one Se’ah of seed (a square measure) which is seventy cubits and a balance (less than eighty) for every partition whose usage is for the airspace, that is to say, to protect the airspace of the fields and vineyards and not to dwell there, we don’t carry there other than with a field requiring one Se’ah of seed/בית סאתים.

לא ישב עליהן – for it is prohibited to use a tree lest one detaches something, but if it is not higher than three [handbreadths], it is permitted to sit upon it.

הדלת שבמוקצה – it is wide, that is behind the house, and its door is not affixed with a hinge like other doors but stands upright against the opening and when he opens it, the door attaches to the ground.

חדקים – thorns that they set up to close with them a breach.

וכן מחלצות – [matting] of reeds – all of these are not attached and are not affixed in their places but when we come too open, we cast them on the ground; therefore, we don’t lock with them for it appears like “building,” other than if they are above the ground, for then, they do not appear like “building” and one can lock things with them.

לא יעמוד אדם ברשות היחיד – and take a key that is placed in the public domain and open with it the door to the store that is placed in the public domain and even though there isn’t from the place of the key to the opening four cubits, as decree lest he would bring in the key near him.

אא"כ עשו לו מחיצה – and stand in it and open it and/or lock it.

אמרו לו ולהא מעשה בשוק של פטמים – the Rabbis heard Rabbi Meir for just as when he said that a person should not stand in the private domain and open [a door] that is in the public domain, this is how it should also be understood: a person should not stand in a Karmelit and open [a door] in the private domain and/or stand in the private domain and open in the Karmelit, and because of this when he gives him from the crammers’ market (where animals are fattened for sale or who deals in such) that was in Jerusalem which is a Karmelit, since its doors are locked at night, it is not a called a public domain, and the window where they place the key was in the private domain, they would stand in the Karmelit and open it the private domain.

פטמין – butchers who fatten animals to slaughter, but the Halakha is not according to Rabbi Meir, neither in the public domain nor in the Karmelit.

של צמרים – sellers of wool.
