שבועות ז׳Shevuot 7

Mishnah 1א׳

כָּל הַנִּשְׁבָּעִין שֶׁבַּתּוֹרָה, נִשְׁבָּעִין וְלֹא מְשַׁלְּמִין. וְאֵלּוּ נִשְׁבָּעִין וְנוֹטְלִין, הַשָּׂכִיר, וְהַנִּגְזָל, וְהַנֶּחְבָּל, וְשֶׁכְּנֶגְדּוֹ חָשׁוּד עַל הַשְּׁבוּעָה, וְהַחֶנְוָנִי עַל פִּנְקָסוֹ. הַשָּׂכִיר כֵּיצַד, אָמַר לוֹ תֶּן לִי שְׂכָרִי שֶׁיֵּשׁ לִי בְיָדֶךָ, הוּא אוֹמֵר נָתַתִּי, וְהַלָּה אוֹמֵר לֹא נָטַלְתִּי, הוּא נִשְׁבָּע וְנוֹטֵל. רַבִּי יְהוּדָה אוֹמֵר, עַד שֶׁתְּהֵא שָׁם מִקְצָת הוֹדָאָה. כֵּיצַד, אָמַר לוֹ תֶּן לִי שְׂכָרִי חֲמִשִּׁים דִּינָר שֶׁיֵּשׁ לִי בְיָדֶךָ, וְהוּא אוֹמֵר הִתְקַבַּלְתָּ דִינַר זָהָב:

All who [need to] swear by Biblical decree, swear and do not pay. The following swear and receive, the hired laborer, the victim of theft, the wounded person, if the opponent is suspected of an oath [of swearing falsely], and the shopkeeper concerning his journal. The hired laborer, how so [what are the circumstances]? If one said to him, give me my wage that is mine that you have, and he says, I gave [it], and this one says, I did not receive it, he swears and receives. Rabbi Yehudah says, [there is no oath] until there is a partial admission. How so? If he said to him, give me my wage of fifty dinar that is mine that you have, and he says, you already received a golden dinar [worth 25 dinar].

Mishnah 2ב׳

הַנִּגְזָל כֵּיצַד, הָיוּ מְעִידִין אוֹתוֹ שֶׁנִּכְנַס לְבֵיתוֹ לְמַשְׁכְּנוֹ שֶׁלֹּא בִרְשׁוּת, הוּא אוֹמֵר כֵּלַי נָטַלְתָּ, וְהוּא אוֹמֵר לֹא נָטַלְתִּי, הֲרֵי זֶה נִשְׁבָּע וְנוֹטֵל. רַבִּי יְהוּדָה אוֹמֵר, עַד שֶׁתְּהֵא שָׁם מִקְצָת הוֹדָאָה. כֵּיצַד, אָמַר לוֹ שְׁנֵי כֵלִים נָטַלְתָּ, וְהוּא אוֹמֵר לֹא נָטַלְתִּי אֶלָּא אֶחָד:

The victim of theft, how so[do they collect and swear]? If they had testified against him that he entered his [his debtor's] house, for his pledge without permission, he says, you took a vessel, and he says, I did not take [it], he swears and receives. Rabbi Yehudah says, [there is no oath] until there is a partial admission. How so? If he said to him, you took two vessels, and he says, I only took one.
