Mishnah 1א׳

אֵלּוּ הֵן הַגּוֹלִין, הַהוֹרֵג נֶפֶשׁ בִּשְׁגָגָה. הָיָה מְעַגֵּל בְּמַעְגִּילָה וְנָפְלָה עָלָיו וַהֲרָגַתּוּ, הָיָה מְשַׁלְשֵׁל בְּחָבִית וְנָפְלָה עָלָיו וַהֲרָגַתּוּ, הָיָה יוֹרֵד בְּסֻלָּם וְנָפַל עָלָיו וַהֲרָגוֹ, הֲרֵי זֶה גוֹלֶה. אֲבָל אִם הָיָה מוֹשֵׁךְ בְּמַעְגִּילָה וְנָפְלָה עָלָיו וַהֲרָגַתּוּ, הָיָה דוֹלֶה בְחָבִית וְנִפְסַק הַחֶבֶל וְנָפְלָה עָלָיו וַהֲרָגַתּוּ, הָיָה עוֹלֶה בְסֻלָּם וְנָפַל עָלָיו וַהֲרָגוֹ, הֲרֵי זֶה אֵינוֹ גוֹלֶה. זֶה הַכְּלָל, כֹּל שֶׁבְּדֶרֶךְ יְרִידָתוֹ, גּוֹלֶה. וְשֶׁלֹּא בְדֶרֶךְ יְרִידָתוֹ, אֵינוֹ גוֹלֶה. נִשְׁמַט הַבַּרְזֶל מִקַּתּוֹ וְהָרַג, רַבִּי אוֹמֵר, אֵינוֹ גוֹלֶה. וַחֲכָמִים אוֹמְרִים, גּוֹלֶה. מִן הָעֵץ הַמִּתְבַּקֵּעַ, רַבִּי אוֹמֵר, גּוֹלֶה. וַחֲכָמִים אוֹמְרִים, אֵינוֹ גוֹלֶה:

The following are exiled [to the Ir Miklat]: one who kills a peron accidentally. If he was pushing a roller [on a roof] and it fell on him[a bystander] and killed him, or if he was lowering a barrel [from a roof] and it fell and killed him [a bystander], or if he was descending a ladder and he fell and killed him[a bystander], all of these cases he [the killer] is exiled. However, if he was pulling a roller and it fell and killed the person, or if he was raising a barrel and the rope tore and it fell and killed a person, or if he was climbing a ladder and he fell and killed a person, in these cases he [the killer] would not exiled. This is the principle: If the killer was involved in a downward movement , he is exiled. If it is not a downward movement he is not exiled. If the blade came off the handle and killed, Rebbi says he is not exiled but the Sages say he is exiled. If it came from the wood being chopped, Rebbi says he is exiled but the Sages say he is not exiled.

Mishnah 2ב׳

הַזּוֹרֵק אֶבֶן לִרְשׁוּת הָרַבִּים וְהָרַג, הֲרֵי זֶה גּוֹלֶה. רַבִּי אֱלִיעֶזֶר בֶּן יַעֲקֹב אוֹמֵר, אִם מִכְּשֶׁיָּצְאתָה הָאֶבֶן מִיָּדוֹ הוֹצִיא הַלָּז אֶת רֹאשׁוֹ וְקִבְּלָהּ, הֲרֵי זֶה פָטוּר. זָרַק אֶת הָאֶבֶן לַחֲצֵרוֹ וְהָרַג, אִם יֵשׁ רְשׁוּת לַנִּזָּק לִכָּנֵס לְשָׁם, גּוֹלֶה. וְאִם לָאו, אֵינוֹ גוֹלֶה, שֶׁנֶּאֱמַר (דברים יט) וַאֲשֶׁר יָבֹא אֶת רֵעֵהוּ בַיַּעַר, מַה הַיַּעַר רְשׁוּת לַנִּזָּק וְלַמַּזִּיק לִכָּנֵס לְשָׁם, יָצָא חֲצַר בַּעַל הַבַּיִת שֶׁאֵין רְשׁוּת לַנִּזָּק וְלַמַּזִּיק לִכָּנֵס לְשָׁם. אַבָּא שָׁאוּל אוֹמֵר, מַה חֲטָבַת עֵצִים רְשׁוּת, יָצָא הָאָב הַמַּכֶּה אֶת בְּנוֹ, וְהָרַב הָרוֹדֶה אֶת תַּלְמִידוֹ, וּשְׁלִיחַ בֵּית דִּין:

One who throws a rock into the public domain and it kills someone, he is exiled. Rabbi Eliezer ben Yaakov says: if the person stuck his head into the public domain only after the stone left his [the killer's] hand, he is exempt. If he threw the stone into his courtyard and it killed, if the victim had permission to be there, he is exiled, but if he did not have permission, he is not exiled, as it says, "If he comes upon his fellow in the woods..." (Deuteronomy 19:5). Just as the woods is open to both the victim and the perpetrator to enter there, this excludes a privately owned courtyard where both the victim (and the perpetrator) does not have permission to be there. Aba Shaul says: Just as chopping wood is optional, [so too one is only exiled for optional activities] this excludes a father beating his son, a teacher disciplining his student, and the messenger of the courts.
