1) THE SELLER ACCESSING HIS PIT (Yerushalmi Halachah 2 Daf 13b)

משנה ולא את הבור ולא את הדות אע"פ שכתב לו עומקה ורומה

(a) (Mishnah): Nor (does the sale of a house) include the pit or stone-walled pit, even though he wrote in the sale document, that he is selling "its lower and higher parts".

וצריך ליקח לו דרך דברי רבי עקיבה

(b) R. Akiva: If the seller wishes to reach his pit (that was not part of the sale), he must pay for access, since the sale included all of the field (even the section that is now needed for the owner to be able to walk to his pit).

וחכמים אומרים אינו צריך ליקח לו דרך

(c) Chachamim: He does not need to pay (as his sale did not include the area of this path).

ומודה ר' עקיבה בזמן שאמר לו חוץ מאילו שאינו צריך ליקח לו דרך

(d) R. Akiva agrees that if he explicitly excluded the pit and stone-walled pit in the sale document, he does not need to pay the buyer for access.

מכרן לאחר ר' עקיבה אומר אינו צריך ליקח לו דרך

(e) If the seller sold the pit to someone else, R. Akiva says that the new pit owner does not need to buy the access path from the new house owner.

וחכמים אומרים צריך ליקח לו דרך:

(f) Chachamim: He does need to buy it.

גמרא לאיזה דבר כתב עומקה ורומה

(g) (Gemara) - question: If the sale does not include the pit, what was the purpose of the seller writing, "its lower and higher parts" into the document?

שאם רצה להשפיל ישפיל הגביה יגביה.

(h) Answer: So that if the buyer wishes to dig his own pits etc., he is permitted; otherwise, he would not be permitted.

רבה בר רב הונא בשם רב הלכה כרבי עקיבה דידן דהוא רבנן דרבי חייה.

(i) Rabbah bar Rav Huna citing Rav: The Halachah follows R. Akiva in our Mishnah, which is also found in the Beraisa of R. Chiya.

ר' זעירא רב ירמיה בשם רב הלכה כרבי עקיבה דרבי חייה דהוא רבנן דבבלאי.

(j) R. Zeira/ Rav Yirmiyah citing Rav: The Halachah follows R. Akiva, because in R. Chiya's Beraisa, the names of R. Akiva and Rabbanan are switched (as will be clear from the continuation of the Gemara).
