Mishnah 1א׳

שְׁנַיִם אוֹחֲזִין בְּטַלִּית, זֶה אוֹמֵר אֲנִי מְצָאתִיהָ וְזֶה אוֹמֵר אֲנִי מְצָאתִיהָ, זֶה אוֹמֵר כֻּלָּהּ שֶׁלִּי וְזֶה אוֹמֵר כֻּלָּהּ שֶׁלִּי, זֶה יִשָּׁבַע שֶׁאֵין לוֹ בָהּ פָּחוֹת מֵחֶצְיָהּ, וְזֶה יִשָּׁבַע שֶׁאֵין לוֹ בָהּ פָּחוֹת מֵחֶצְיָהּ, וְיַחֲלֹקוּ. זֶה אוֹמֵר כֻּלָּהּ שֶׁלִּי וְזֶה אוֹמֵר חֶצְיָהּ שֶׁלִּי, הָאוֹמֵר כֻּלָּהּ שֶׁלִּי, יִשָּׁבַע שֶׁאֵין לוֹ בָהּ פָּחוֹת מִשְּׁלשָׁה חֲלָקִים, וְהָאוֹמֵר חֶצְיָהּ שֶׁלִּי, יִשָּׁבַע שֶׁאֵין לוֹ בָהּ פָּחוֹת מֵרְבִיעַ. זֶה נוֹטֵל שְׁלשָׁה חֲלָקִים, וְזֶה נוֹטֵל רְבִיעַ:

Two are holding a garment. One says, "I found it," and the other says, "I found it." [If] one says, "all of it is mine" and the other says, "all of it is mine." This one shall swear that he owns no less than half of it, and this one shall swear that he owns no less than half of it, and they shall divide it [between them.] [If] one says, "all of it is mine" and the other says "half of it is mine." The one who says "all of it is mine" shall swear that he owns no less than three quarters of it; and the one who says "half of it is mine" shall swear that he owns no less than one quarter of it. He [the former] takes three quarters and he [the latter] takes one quarter.

Mishnah 2ב׳

הָיוּ שְׁנַיִם רוֹכְבִין עַל גַּבֵּי בְהֵמָה, אוֹ שֶׁהָיָה אֶחָד רוֹכֵב וְאֶחָד מַנְהִיג, זֶה אוֹמֵר כֻּלָּהּ שֶׁלִּי, וְזֶה אוֹמֵר כֻּלָּהּ שֶׁלִּי, זֶה יִשָּׁבַע שֶׁאֵין לוֹ בָהּ פָּחוֹת מֵחֶצְיָהּ, וְזֶה יִשָּׁבַע שֶׁאֵין לוֹ בָהּ פָּחוֹת מֵחֶצְיָהּ, וְיַחֲלֹקוּ. בִּזְמַן שֶׁהֵם מוֹדִים אוֹ שֶׁיֵּשׁ לָהֶן עֵדִים, חוֹלְקִים בְּלֹא שְׁבוּעָה:

Two [men] were riding on an animal, or one was riding and one was leading. One says, "all of it is mine," and the other one says, "all of it is mine." This one shall swear that he owns no less than half of it, and the other one shall swear that he owns no less than half of it, and they will divide it. In a situation where they agree, or they have witnesses, they divide it without an oath.
