3)[line 1]מוכר, בעין יפה מוכר / בעין רעה מוכרMOCHER, B'AYIN YAFAH MOCHER / B'AYIN RA'AH MOCHER
Rebbi Akiva and the Chachamim argue about what the mindset of a seller is when he sells property without specifying if he is keeping anything for himself. "Mocher, b'Ayin Yafah Mocher" means that a seller sells with good will and does not keep any part of what he sells for himself, e.g. when a person sells a field and does not sell the well in it, the seller must purchase a path through the field from the buyer in order to be able to get to his well, since he sold the field with "good will," not leaving a path for himself. If the seller sells "b'Ayin Ra'ah," it means that he keeps a certain part of what he is selling for himself.
