וְכִֽי־יַכֶּה֩ אִ֨ישׁ אֶת־עַבְדּ֜וֹ א֤וֹ אֶת־אֲמָתוֹ֙ בַּשֵּׁ֔בֶט וּמֵ֖ת תַּ֣חַת יָד֑וֹ נָקֹ֖ם יִנָּקֵֽם׃
E se alguém ferir seu servo ou sua serva com uma vara, e ele ou ela morrer debaixo de sua mão, certamente será vingado.
Shenei Luchot HaBerit
Commandment 51 provides for the Court to impose the death penalty by the sword in certain situations (Hereg). If a master kills his Canaanite servant by a lethal blow, he is also guilty of execution by this method, viz: (Exodus 21,20) "he shall be avenged." (Leviticus 26,25 states "the sword will wreak vengeance for the covenant" on those breaching it).
