Eruvin 95B

ובסכנה ⁠— מכסן והולך לו.

And in a time of danger, when it is dangerous to tarry outside town, he covers the tefillin and proceeds on his way.

רבי שמעון אומר: נותנן לחבירו, וחבירו לחבירו, עד שמגיע לחצר החיצונה.

R' Shimon says that there is an alternative method of transferring the tefillin: One gives them to another who is less than 4 cubits from him, and the other passes them to another, until the tefillin reach the outermost courtyard of the city. Since carrying less than 4 cubits in a public domain is not prohibited by Torah law, in this case, the rabbis permitted carrying in that manner due to the sanctity of the tefillin.

וכן בנו ⁠— נותנו לחבירו, וחבירו לחבירו, אפילו מאה. רבי יהודה אומר: נותן אדם חבית לחבירו, וחבירו לחבירו, אפילו חוץ לתחום. אמרו לו: לא תהלך זו יותר מרגלי בעליה.

And similarly, with regard to one’s son who was born in a field and may not be carried on Shabbat, since that is akin to carrying a burden in the public domain: One gives him to another, and the other passes him to another, even if it requires 100 people. R' Yehuda says: A person may even give a jug to another, and the other may pass it to another, and in that way even take it beyond the Shabbat limit, provided that no one person carries it more than 4 cubits. They said to him: This jug may not go a greater distance than the feet of its owner, i.e., it may not be carried any farther than its owner may walk.

גמ׳ זוג אחד אין, טפי ⁠— לא. לימא תנן סתמא דלא כרבי מאיר?

Talmud: We learned in the Mishnah that a person who finds tefillin in a field may carry them by pairs, indicating that one pair, yes, it may be carried; however, more than one pair, no, they may not be carried. The Talmud asks: Let us say that we learned the unattributed Mishnah not in accordance with the opinion of R' Meir, despite the principle that an unattributed Mishnah usually reflects R' Meir’s opinion.
