מתני׳ ואלו הן שמצילין אותן בנפשן הרודף אחר חבירו להרגו ואחר הזכר ואחר הנערה המאורסה אבל הרודף אחר בהמה והמחלל את השבת ועובד עבודת כוכבים אין מצילין אותן בנפשן:
MISHNA: And these are the ones who are saved from transgressing even at the cost of their lives; that is to say, these people may be killed so that they do not perform a transgression: One who pursues another to kill him, or pursues a male to sodomize him, or pursues a betrothed young woman to rape her. But with regard to one who pursues an animal to sodomize it, or one who seeks to desecrate Shabbat, or one who is going to engage in idol worship, they are not saved at the cost of their lives. Rather, they are forewarned not to transgress, and if they proceed to transgress after having been forewarned, they are brought to trial, and if they are found guilty, they are executed.
Similarly, this commandment applies when a person sees a colleague drowning at sea or being attacked by robbers or a wild animal, and he can save him himself or can hire others to save him. Similarly, it applies when he hears gentiles or mosrim conspiring to harm a colleague or planning a snare for him, and he does not inform him and notify him of the danger.
And it applies when a person knows of a gentile or a man of force who has a complaint against a colleague, and he can appease the aggressor on behalf of his colleague, but he fails to do so. And similarly, in all analogous instances, a person who fails to act transgresses the commandment: "Do not stand idly by while your brother's blood is at stake."
מתני' ואלו שמצילין אותן - מן העבירה:
and those who save them - from the offense...
What girl who is betrothed can be saved - from the crime in his soul, even a murderer, etc. And my sister will heal a girl from a murderer who is killed and do not pass as follows and who is this I will not envy the words of Dr. Dagg Garra Atia:...
If one pursues an animal with the intent of sodomizing it, or one seeks to perform a forbidden labor on the Sabbath or to worship idols - although the Sabbath and the prohibition against idol worship are fundamental elements of our faith - the person should not be killed until he commits the transgression and is brought to court, convicted and executed.
