הַמַּכֶּה אֶת חֲבֵרוֹ בְּזָדוֹן בְּאֶבֶן אוֹ בְּעֵץ וֶהֱמִיתוֹ. אוֹמְדִין דָּבָר שֶׁהִכָּהוּ בּוֹ וּמָקוֹם שֶׁהִכָּה עָלָיו. אִם רָאוּי אוֹתוֹ חֵפֶץ לְהָמִית בְּאֵיבָר זֶה אוֹ אֵינוֹ רָאוּי. שֶׁנֶּאֱמַר (במדבר לה יז) "בְּאֶבֶן יָד אֲשֶׁר יָמוּת בָּהּ הִכָּהוּ" (במדבר לה יח) "אוֹ בִּכְלִי עֵץ יָד אֲשֶׁר יָמוּת בּוֹ הִכָּהוּ". עַד שֶׁיִּהְיֶה בּוֹ כְּדֵי לְהָמִית. וְאֵינוֹ דּוֹמֶה מַכֵּהוּ עַל לִבּוֹ לְמַכֵּהוּ עַל יְרֵכוֹ:
The following rule applies when a person strikes a colleague intentionally with a stone or a piece of wood and causes his death. We assess the object with which he was struck, and the place where he was struck, and determine whether or not it is likely that such an article would cause death when used to give a blow in such a place. This is implied by Numbers 35:17-18, which states: "If he struck him with a fist-sized stone that could cause death... or if he struck him with a fist-sized wooden article that could cause death." "That could cause death" teaches that the murder weapon must be such that would likely cause him to die. Striking a person on his heart cannot be compared to striking him on his thigh.
