13וְכֵן אִם הָיָה שָׁם עֵד אֶחָד בִּלְבַד וּבַעַל הַבַּיִת טוֹעֵן שֶׁגָּזוּל הוּא כְּלִי זֶה בְּיָדוֹ וְהַלָּה אוֹמֵר לָקוּחַ הוּא בְּיָדִי אוֹ בְּחוֹב גְּבִיתִיו אוֹ שֶׁלִּי הָיָה וּפִקָּדוֹן הוּא אֶצְלְךָ הֲרֵי זֶה חַיָּב לְהַחְזִיר הַכְּלִי לִבְעָלָיו בְּלֹא שְׁבוּעָה שֶׁאִלּוּ הָיוּ שָׁם שְׁנֵי עֵדִים הָיָה חַיָּב לְשַׁלֵּם וְעַכְשָׁו שֶׁאֵין שָׁם אֶלָּא עֵד אֶחָד חַיָּב שְׁבוּעָה וְאֵינוֹ יָכוֹל לִשָּׁבַע שֶׁהֲרֵי אֵינוֹ מַכְחִישׁ אֶת הָעֵד וְכָל הַמְחֻיָּב שְׁבוּעָה וְאֵינוֹ יָכוֹל לִשָּׁבַע מְשַׁלֵּם. לְפִיכָךְ אִם כָּפַר וְאָמַר לֹא נִכְנַסְתִּי לְבֵיתוֹ וְלֹא נָטַלְתִּי כְּלוּם הוֹאִיל וְאֵין שָׁם אֶלָּא עֵד אֶחָד וְהוּא מַכְחִישׁוֹ הֲרֵי זֶה נִשְׁבָּע שְׁבוּעַת הַתּוֹרָה שֶׁלֹּא לָקַח מִבֵּיתוֹ כְּלוּם וְנִפְטָר:
Similarly, if only one witness observed the intruder taking the article, and the homeowner claims that the intruder robbed him of the article, while the defendant claims that he purchased it, he took it as payment for a debt, or it was his and was entrusted to the homeowner for safekeeping, the intruder is obligated to return the article to the homeowner, and the homeowner is not even required to take an oath. The rationale is that if two witnesses had observed the matter, the defendant would have been obligated to pay. Since there is only one witness, the defendant is required to take an oath. And in this instance he cannot take the oath, because he does not deny the statement of the witness. Therefore, we follow the principle: Whenever a person is obligated to take an oath and cannot take that oath, he must pay. Accordingly, different rules apply if the defendant denied the matter, saying: "I never entered his house, nor did I take anything." Since there is only one witness, and the defendant denies his testimony, he is obligated to take an oath mandated by Scriptural Law, stating that he did not take anything from the home. With this, he is exonerated.
