1) SELLING HALF A FIELD (Yerushalmi Halachah 4 Daf 21a)
משנה האומר לחבירו חצי שדה אני מוכר לך משמנין ביניהן נוטל חצי שדהו
(a) (Mishnah): If a person said to his friend, "I am selling half a field to you", they evaluate the field and divide it (so that each gets half the value of the field, bearing in mind the various qualities of soil that it contains).
חצייה בדרום אני מוכר לך משמנין ונוטל חצייה בדרום והוא מקבל עליו מקום הגדר והחריץ ובין חריץ
(b) If he said, "I am selling you half in the southern side", they evaluate it and the buyer receives a half in the southern side (equivalent to half the field's value); and the buyer receives the area of the fence, a large furrow and a small furrow.
וכמה הוא חריץ ששה טפחים ובין חריץ לשלשה:
(c) How wide is a furrow? Six tefachim. How wide is a secondary furrow? Three tefachim.
גמרא תני האומר לחבירו חצי שדה אני מוכר לך ופלוני מקיפך ופלוני מקיפך וחצי פלוני מקיפך
(d) (Gemara) - Beraisa: One who says to his friend, "I am selling to you half a field and Reuven's property will be one border, and Shimon's property will be another border, and half of Levi's property will be another border"...(For example, the field has neighbors along the east and the south sides and half of the west side.)
רב הונא ורב יהודה ור' ירמיה:
(e) There was a three way disagreement between Rav Huna, Rav Yehuda and R. Yirmiyah as to the meaning of the last part of his statement -
חד אמר נותן לו כמין פנדור
1. One said that he gives him a strip of the field like a money belt (that has a wider part in the middle for the money and narrow parts on each side the strap around the body. He gives him a wide strip, as wide as half the western side, along the southern side and a narrow strip along the entire eastern side);
וחד אמר נותן לו כמין מטלית
2. One said that he gives him a rectangular shaped piece of land like a cloth (meaning that he simply gives him a wide strip, as wide as half the western side, along the southern side);
וחד אמר נותן לו כמין פסיקיא
3. One said that he gives him land like a wide belt (that has wide sides as well. This means that he gives him a strip along all of the three sides - the eastern, the southern, and the western sides.)
