Mishnah 1א׳

הַמַּפְקִיד אֵצֶל חֲבֵרוֹ בְּהֵמָה אוֹ כֵלִים, וְנִגְנְבוּ אוֹ שֶׁאָבְדוּ, שִׁלֵּם וְלֹא רָצָה לִשָּׁבַע, שֶׁהֲרֵי אָמְרוּ שׁוֹמֵר חִנָּם נִשְׁבָּע וְיוֹצֵא, נִמְצָא הַגַּנָּב, מְשַׁלֵּם תַּשְׁלוּמֵי כֶפֶל. טָבַח וּמָכַר, מְשַׁלֵּם תַּשְׁלוּמֵי אַרְבָּעָה וַחֲמִשָּׁה. לְמִי מְשַׁלֵּם, לְמִי שֶׁהַפִּקָּדוֹן אֶצְלוֹ. נִשְׁבַּע וְלֹא רָצָה לְשַׁלֵּם, נִמְצָא הַגַּנָּב, מְשַׁלֵּם תַּשְׁלוּמֵי כֶפֶל, טָבַח וּמָכַר, מְשַׁלֵּם תַּשְׁלוּמֵי אַרְבָּעָה וַחֲמִשָּׁה. לְמִי מְשַׁלֵּם, לְבַעַל הַפִּקָּדוֹן:

[If] one deposited [for safekeeping] an animal or vessels with his neighbor and they were stolen or lost, if he paid and did not want to swear [the prescribed oath], because they [the sages] said that an unpaid guardian must swear and be exempt [from liability, and if afterward] the thief is found, he must pay double. [If the thief] butchered or sold the object, he must pay four or fivefold. To whom does he pay? To him who [kept] the deposit with him. [If the guardian] swore the [prescribed oath] and did not want to pay, and [afterward] the thief is found, he must pay double. [If the thief] butchered or sold the object, he must pay four or fivefold. To whom does he pay? To the owner of the deposit.

Mishnah 2ב׳

הַשּׂוֹכֵר פָּרָה מֵחֲבֵרוֹ וְהִשְׁאִילָהּ לְאַחֵר, וּמֵתָה כְדַרְכָּה, יִשָּׁבַע הַשּׂוֹכֵר שֶׁמֵּתָה כְדַרְכָּה, וְהַשּׁוֹאֵל יְשַׁלֵּם לַשּׂוֹכֵר. אָמַר רַבִּי יוֹסֵי, כֵּיצַד הַלָּה עוֹשֶׂה סְחוֹרָה בְּפָרָתוֹ שֶׁל חֲבֵרוֹ, אֶלָּא תַחֲזֹר פָּרָה לַבְּעָלִים:

If one rented a cow from his neighbor, and loans it to another, and the cow dies naturally; the one who rented [the cow] should swear that it died naturally, and the borrower should pay the renter. Rabbi Yosei said: How shall he do business with his neighbor's cow? Rather, the cow [or its value] must be returned to the owners.
