The Mishnah in Gittin 27a says the following:
המביא גט ואבד הימנו מצאו לאלתר כשר ואם לאו פסול מצאו בחפיסה או בדלוסקמא אם מכירו כשר
If a person is bringing a Get and loses it, if he finds it immediately, it is Kosher, if not, it is Pasul. If it is found in his container, and he sells it, it is Kosher.
Source: My own translation.
This Gemara didn't make so much sense to me. I know there's a rule that a Get has to be written Lishma.
- So how can this Get, which was clearly written for one woman be sold to another?
- And what does the fact that it was found in his container have anything to do with it?
I'm really looking for some clarification in this Gemara. Someone told me to look it up in artscroll, but I'm not so good with big english words, so I hope someone here might give me simpler pshat.
