* Judah ha-Levi, "Cuzari," iii. 73, although only those laws which are found in the Torah, before the revelation at Sinai, should, it would seem, be binding upon all mankind, yet the Rabbis discarded some and, by hermeneutic rules or in accordance with some tradition, introduced others which are not found there.
* Teshuvot Chachmai Provance 48 which clearly distinguishes between regulations based on the Noachide laws and regulations based on the law of the land or the law of the king.
* Kesef Mishneh on Sanhedrin 57b, In the case of murder, if the Noachide slay a child in its mother's womb, or kill a person whose life is despaired of ("ṭerefah"), or if he cause the death of a person by starving him or by putting him before a lion so that he can not escape, or if he slay a man in self-defense, the Noachide is guilty of murder and must pay the death-penalty, although under the same circumstances an Israelite would not be executed
* Leḥem Mishneh & Kesef Mishneh on Sanhedrin 74b, The Noachid is free from punishment if he commits a sin unwittingly; ignorance of the Law, however, does not excuse him. If he commits a sin under duress, even one for which an Israelite is obliged to undergo martyrdom rather than transgress (e.g., idolatry, adultery, or murder), he is not liable to punishment
