לו בְּכָל אֵלּוּ אֵינוֹ יוֹצֵא לְחֵרוּת עַד שֶׁיַּעֲשֶׂה הָאָדוֹן בְּכַוָּנָה. לְפִיכָךְ אִם כִּוֵּן לִזְרֹק אֶבֶן בִּבְהֵמָה, וְנָפְלָה בָּעֶבֶד, וְחָתְכָה אֶצְבָּעוֹ אוֹ הִפִּיל שִׁנּוֹ, אֵינוֹ יוֹצֵא לְחֵרוּת. וְכֵן אִם הוֹשִׁיט יָדוֹ לִמְעֵי שִׁפְחָתוֹ, וְסִמֵּא עֵין עֻבָּר שֶׁבְּמֵעֶיהָ, אֵינוֹ יוֹצֵא לְחֵרוּת שֶׁהֲרֵי לֹא יָדַע דָּבָר שֶׁיִּתְכַּוֵּן לוֹ. אֲבָל אִם הָיָה רַבּוֹ רוֹפֵא וְאָמַר לֵיהּ: כְּחֹל עֵינַי, וְסִמְּאָהּ, יוֹצֵא לְחֵרוּת שֶׁהֲרֵי כִּוֵּן לָאֵבֶר.

In all these cases the slave doesn’t go free for actions done unintentionally by the owner. Thus if the master intended to hit an animal with a rock but instead hit the slave and cut a finger or knocked out a tooth the slave does not go free. And If the master inserted his hand into the womb of his maid-servant and blinded the eye of the fetus within, he is not granted his freedom, for he was not aware of the entity thus he could intend to strike it. However if the Master is the slaves doctor

and the slave told him: “Treat my eye for me,” and he ends up blinded it, the slave goes free because his intention/attention was on the Limb/Organ.
