Jerusalem Talmud Bava Metzia 3.7

משנה: הַמַּפְקִיד מָעוֹת אֵצֶל חֲבֵירוֹ צְרָרָן וְהִפְשִׁילָן לַאֲחוֹרָיו אוֹ שֶׁמְּסָרָן לִבְנוֹ אוֹ לְבִתּוֹ הַקְּטַנִּים וְנָעַל בִּפְנֵיהֶן שֶׁלֹּא כָרָאוּי חַיָיב שֶׁלֹּא שָׁמַר כְּדֶרֶךְ הַשּׁוֹמְרִין וְאִם שָׁמַר כְּדֶרֶךְ הַשּׁוֹמְרִים פָּטוּר.

MISHNAH: If somebody deposits coins with another person who binds them together and carries them on his back or gives them to his underage son or daughter, or locks them insufficiently, he is liable because he did not take care the way people take care. But if he took care the way people take care, he is not liable.

הלכה: הַמַּפְקִיד מָעוֹת אֵצֶל חֲבֵירוֹ כול׳. אָמַר רִבִּי יוֹסֵי. וְתִשְׁמַע מִינָּהּ. בַּר נַשׁ דִּיהַב לְחַבְרֵיהּ פליטורין בַּשּׁוּקָא. מְסָרָן לִבְנוֹ וּבִתּוֹ הַקְּטַנִּים נִגְנְבוּ אוֹ אָבְדוּ פָּטוּר מִלְּשַׁלֵּם. שֶׁאֲנִי אוֹמֵר. לֹא עַל דַּעַת פליטורין בַּשּׁוּק.

HALAKHAH: “If somebody deposits coins with another person,” etc. Rebbi Yose said: One understands from this that in case a man gave plyṭvryn to another in the market place and that one handed it over to his underage son or daughter, if they were stolen or lost he is not liable since I say that nobody is in the market place because of plyṭvryn.

מָתַי אָמְרוּ. שׁוֹמֵר חִנָּם נִשְׁבַּע וְיוֹצֵא. בִּזְמַן שֶשִּׁימֵּר כְּדֶרֶךְ הַשּׁוֹמְרִין. נָעַל כָּרָאוּי קָשַׁר כָּרָאוּי נָתְנָן בָּאֲפוּנְדָּתוֹ צְרָרָן בְּסַדִּינוֹ וְהִשְׁלִיכָן לְפָנָיו. נְתָנָן בְּשִׁידָּה וּבְתֵיבָה וּבְמִגְדָּל. נִגְנְבוּ אוֹ אָבְדוּ חַיָיב בִּשְׁבוּעָה וּפָטוּר מִלְּשַׁלֵּם. וְאִם יֵשׁ עֵדִים שֶׁעָשָׂה כֵן אַף מִשְּׁבוּעָה פָטוּר. נָעַל שֶׁלֹּא כָרָאוּי קָשַׁר שֶׁלֹּא כָרָאוּי הִפְשִׁילָן לַאֲחוֹרָיו נְתָנָן בְּרֹאשׁ גַּגּוֹ וְנִגְנְבוּ חַיָיב לְשַׁלֵּם. נְתָנָן בְּמָקוֹם שֶׁנּוֹהֵג לִיתֵּן שֶׁלּוֹ אִם הָיָה רָאוּי לִשְׁמִירָה פָטוּר וְאִי לֹא חַיָיב.

When did they say that the unpaid trustee swears and is absolved? If he took care of it the way caretakers do: He locked as he should, tied as he should, put it into his money-belt, tied it into his poncho and kept it in front of him, put it into a cupboard, a chest, or a safety box; if they were stolen or lost he is required to swear but not liable to pay. If there are witnesses that he did so, he even is freed from the oath. He locked carelessly, tied carelessly, put it on his back, left it on his roof; if it was stolen he is liable for payment. If he put it at a place where he usually keeps his own things, if it was kept safe as it should have been he is not liable, otherwise he is liable.
