Mishnah 1א׳
שְׁבוּעַת הָעֵדוּת נוֹהֶגֶת בַּאֲנָשִׁים וְלֹא בְנָשִׁים, בִּרְחוֹקִין וְלֹא בִקְרוֹבִין, בִּכְשֵׁרִים וְלֹא בִפְסוּלִין. וְאֵינָהּ נוֹהֶגֶת אֶלָּא בָרְאוּיִין לְהָעִיד, בִּפְנֵי בֵית דִּין וְשֶׁלֹּא בִּפְנֵי בֵית דִּין, מִפִּי עַצְמוֹ, וּמִפִּי אֲחֵרִים, אֵין חַיָּבִין עַד שֶׁיִּכְפְּרוּ בָהֶן בְּבֵית דִּין, דִּבְרֵי רַבִּי מֵאִיר. וַחֲכָמִים אוֹמְרִים, בֵּין מִפִּי עַצְמוֹ וּבֵין מִפִּי אֲחֵרִים, אֵינָן חַיָּבִין עַד שֶׁיִּכְפְּרוּ בָהֶן בְּבֵית דִּין:
The oath of testimony applies to men but not to women, to relatives and non- relatives, and by those fit but not by those unfit. It only applies to those who are fit to testify, whether before a court or not before a court, by oneself, and by others. They [the witnesses] are not liable unless they deny it [their knowledge] before a court, these are the words of Rabbi Meir. The Sages say: whether it was by oneself or by others, they are not liable unless they deny it before a court.
Mishnah 2ב׳
וְחַיָּבִין עַל זְדוֹן הַשְּׁבוּעָה, וְעַל שִׁגְגָתָהּ עִם זְדוֹן הָעֵדוּת, וְאֵינָן חַיָּבִין עַל שִׁגְגָתָהּ. וּמַה הֵן חַיָּבִין עַל זְדוֹן הַשְּׁבוּעָה, קָרְבָּן עוֹלֶה וְיוֹרֵד:
And they are liable for an intentional transgression of the oath and for its unintentional transgression with an intentional denial of the testimony, but they are not liable for an unintentional act. What are they liable for in an intentional oath? An offering of an Oleh veYored [a sliding-scale Chattat offering where the economic status of the individual determines whether he brings an animal, a bird, or flour].
