The third Noahide Law is "Do not murder." This law prohibits the taking of another human life without just cause, and it is considered a fundamental principle of morality and ethics in many religious and philosophical traditions.
The source of this law can be found in many places in the Bible. It is first mentioned in the book of Genesis, which states:
The law is also the third of The Ten Commandments:
These verses emphasize the sacredness of human life and underscore the seriousness of taking another person's life without just cause. They also provide the basis for the concept of capital punishment in Jewish law and tradition.
The Talmud expands on the prohibition against murder and its implications for ethical living. For example, it teaches (Sanhedrin 37a) that anyone who destroys a single life is considered to have destroyed an entire world, while anyone who saves a single life is considered to have saved an entire world:
Whoever destroys a soul, it is considered as if he destroyed an entire world. And whoever saves a life, it is considered as if he saved an entire world.
The Talmud (Sanhedrin 57b) provides additional commentary on this law, stating that it applies to any human being, regardless of race or religion. Furthermore, it specifies that the law not only prohibits outright murder, but also any action that could lead to someone's death, such as withholding food or medicine from someone in need.
Maimonides, a medieval Jewish philosopher and scholar, in his Mishneh Torah, Laws of Murder and Life Preservation 1:1, explains that this law applies to all forms of murder, including intentional, accidental, and indirect (such as through neglect or lack of concern for another's life). He also explains that the penalty for violating this law is death by a court of law.
The Noachide Code, compiled by Rabbi Moshe Weiner, explains that the prohibition against murder includes taking the life of an innocent person, whether through direct or indirect means. It also prohibits any actions that endanger someone's life, such as reckless driving or physical violence.
Jewish law, as outlined in the Mishnah and the Talmud, provides specific guidelines for cases in which the taking of a human life is justified, such as in self-defense or in cases of capital punishment. These guidelines emphasize the importance of protecting and preserving human life, while also recognizing the need for justice and accountability.
Maimonides further elaborates (Mishneh Torah, Laws of Personal Injury and Damage, 1:1) that the prohibition against murder includes not only the act of taking another person's life, but also any act of violence or harm towards another person:
It is forbidden to cause injury to any person, whether by deed or word, and it is a greater sin to cause injury to a Torah scholar.
This underscores the importance of treating all human beings with respect and dignity, regardless of their social status or background.
The third Noahide Law prohibits taking the life of an innocent person, whether directly or indirectly, and includes all forms of murder, intentional or accidental, as well as any actions that endanger someone's life through reckless behavior that could lead to harm. The law has practical implications for ethical living as well. By recognizing the sacredness of human life and the importance of treating all human beings with respect and dignity, we are called upon to live our lives in accordance with moral and ethical principles. This includes treating others with kindness and compassion, and avoiding any acts of violence or harm towards another person.
