וַתִּפֹּל֙ עַל־פָּנֶ֔יהָ וַתִּשְׁתַּ֖חוּ אָ֑רְצָה וַתֹּ֣אמֶר אֵלָ֗יו מַדּוּעַ֩ מָצָ֨אתִי חֵ֤ן בְּעֵינֶ֙יךָ֙ לְהַכִּירֵ֔נִי וְאָּנֹכִ֖י נָכְרִיָּֽה׃
路得就俯伏在地，向他叩拜，對他說：«我是個外邦女子，為甚麼竟蒙你恩待，這樣眷顧我呢？»
Mishnah Eruvin
One who finds tefillin should bring them in one pair at a time. Rabban Gamaliel says: two pairs at a time. To what does this apply? To old ones but in the case of new ones he is exempt. If he found them arranged in a set or in bundles he shall wait by them until it is dark and then bring them in. In a time of danger, he should cover them and walk away.
