הַתּוֹבֵעַ עֵדָיו לְהָעִיד לוֹ עֵדוּת שֶׁיִּתְחַיֵּב הַנִּתְבָּע בְּעֵדוּתָן לְבַדָּהּ לִתֵּן לְתוֹבֵעַ זֶה מָמוֹן הַמִּטַּלְטֵל. וְכָפְרוּ בְּעֵדוּתָן וְנִשְׁבְּעוּ. בֵּין שֶׁנִּשְׁבְּעוּ בְּבֵית דִּין בֵּין שֶׁנִּשְׁבְּעוּ חוּץ לְבֵית דִּין הֲרֵי אֵלּוּ חַיָּבִין מִשּׁוּם שְׁבוּעַת הָעֵדוּת. שֶׁהֲרֵי הִפְסִידוּהוּ מָמוֹן בִּכְפִירָתָם. וְכֵן אִם הִשְׁבִּיעָם הַתּוֹבֵעַ וְכָפְרוּ בּוֹ אַף עַל פִּי שֶׁלֹּא נִשְׁבְּעוּ הֵן וְלֹא עָנוּ אָמֵן אַחַר שְׁבוּעָתוֹ כֵּיוָן שֶׁכָּפְרוּ הֲרֵי אֵלּוּ חַיָּבִין. וְהוּא שֶׁיַּשְׁבִּיעֵם בְּבֵית דִּין:
When a plaintiff demands that witnesses testify concerning a matter that through their testimony alone will obligate the defendant to pay this plaintiff a financial claim involving moveable property, [the witnesses] denied [knowing] testimony and took an oath to this effect - whether in a court of law or outside of it - they are liable for sh'vuat haedut, for they caused the plaintiff a financial loss through their denial. Similarly, if the plaintiff administered an oath to them and they denied the matter, [they are liable] even though they did not take an oath or answer Amen to the oath he [administered]. Since they denied the matter, they are liable, provided he administered the oath to them in court.
