שׁוֹר שֶׁנָּגַח אֶת הַפָּרָה וְנִמְצָא עֻבָּרָהּ בְּצִדָּהּ, וְאֵין יָדוּעַ אִם עַד שֶׁלֹּא נְגָחָהּ יָלְדָה, אִם מִשֶּׁנְּגָחָהּ יָלְדָה, מְשַׁלֵּם חֲצִי נֶזֶק לַפָּרָה וּרְבִיעַ נֶזֶק לַוָּלָד.  וְכֵן, פָּרָה שֶׁנָּגְחָה אֶת הַשּׁוֹר וְנִמְצָא וְלָדָהּ בְּצִדָּהּ, וְאֵין יָדוּעַ אִם עַד שֶׁלֹּא נָגְחָה יָלְדָה, אִם מִשֶּׁנָּגְחָה יָלְדָה, מְשַׁלֵּם חֲצִי נֶזֶק מִן הַפָּרָה וּרְבִיעַ נֶזֶק מִן הַוָּלָד.
