14יֵרָאֶה לִי שֶׁהַמַּכֶּה אֶת עַבְדּוֹ בְּסַכִּין וְסַיִף אוֹ בְּאֶבֶן וְאֶגְרוֹף וְכַיּוֹצֵא בָּהֶן וַאֲמָדוּהוּ לְמִיתָה וּמֵת אֵינוֹ בְּדִין (שמות כא כא) "יוֹם אוֹ יוֹמַיִם" אֶלָּא אֲפִלּוּ מֵת לְאַחַר שָׁנָה נֶהֱרָג עָלָיו. לְכָךְ נֶאֱמַר (שמות כא כ) "בַּשֵּׁבֶט" שֶׁלֹּא נָתְנָה תּוֹרָה רְשׁוּת לְהַכּוֹתוֹ אֶלָּא בְּשֵׁבֶט וּמַקֵּל וּרְצוּעָה וְכַיּוֹצֵא בָּהֶן וְלֹא בְּהַכָּאַת רְצִיחָה:
It appears to me that when a person strikes his servant with a knife, a sword, a stone, a fist or the like, and it was assessed that he would die, and he did die, the leniency granted if the servant survives more than 24 hours does not apply. Instead, even if the servant dies a year later, the owner should be executed because of the servant's death. To underscore this point, Exodus 21:20 mentions striking the servant "with a rod." For the Torah has granted the owner permission to beat his servant only with a rod, a staff, a strap or the like, and he may not strike him with murderous blows.
