Eiruvin 10:2-3

Eiruvin 10:2

Rabbi Shimon says that the one who finds tefillin on Shabbos should hand them to a friend, who hands them to another friend, and from him to another friend, and so on until they reach the first courtyard in town. This same procedure should be followed if a baby is born in the fields on Shabbos, even if the baby is passed to 100 people. Rabbi Yehuda says that one may pass a barrel to his friend and from him to the next friend, etc. even if they pass it beyond the Shabbos boundary (techum). The Sages responded that an object can only go on Shabbos where its owner can go.

Eiruvin 10:3

If a person was reading a scroll on his doorstep and it rolled out from his hand, he may roll it back to him. If he was sitting on the roof and the scroll rolled out from his hand, he may roll it back if it does not extend within ten handbreadths of the ground (about 30”). Once it comes within ten handbreadths of the ground, he may no longer roll it back. In such a case, he should simply turn it over so that the writing is face-down. Rabbi Yehuda says that one may roll it back so long as it is even a needle’s width from the ground. Rabbi Shimon says that one may roll it back even if it reaches the ground because the rabbinic safeguards do not supersede treating the Scriptures respectfully.
