The Rambam writes [Yesodei Hatorah 5/4]:
If anyone about whom it is said: "Transgress and do not sacrifice your life," sacrifices his life and does not transgress, he is held accountable for his life.
When anyone about whom it is said: "Sacrifice your life and do not transgress," sacrifices his life and does not transgress, he sanctifies [God's] name. If he does so in the presence of ten Jews, he sanctifies [God's] name in public, like Daniel, Chananiah, Mishael, Azariah, and Rabbi Akivaand his colleagues. These are those slain by [the wicked] kingdom, above whom there is no higher level. Concerning them, [Psalms 44:23] states: "For Your sake, we have been slain all day, we are viewed as sheep for the slaughter," and [Psalms 50:5] states: "Gather unto Me, My pious ones, those who have made a covenant with Me by slaughter."
When anyone about whom it is said: "Sacrifice your life and do not transgress," transgresses instead of sacrificing his life, he desecrates [God's] name. If he does so in the presence of ten Jews, he desecrates [God's] name in public, nullifies [the fulfillment of] the positive commandment of the sanctification of [God's] name, and violates the negative commandment against the desecration of God's name.
Nevertheless, since he was forced to transgress, he is not [punished by] lashing, and, needless to say, is not executed by the court even if he was forced to slay [a person]. The [punishments of] lashes and execution are administered only to one who transgresses voluntarily, [when the transgression is observed by] witnesses, and [when] a warning [was given], as [Leviticus 20:5] states concerning one who gives his children to [the worship of] Molech: "I will turn My face against that person."
The oral tradition teaches [that we can infer]: "that person" and not one who is forced [to transgress, who transgresses] inadvertently, or [who transgresses] because of an error. If, concerning the worship of false gods, which is the most serious [of sins], a person who is forced to worship is not liable for karet, nor, needless to say, execution by a court, how much more so [does this principle apply] regarding the other mitzvot of the Torah? [Similarly,] regarding forbidden sexual relations, [Deuteronomy 22:26] states: "Do not do anything to the maiden."
So the Rambam needs two pesukim [bolded] to prove his point that אנוס is פטור. But in Hilchos Sanhedrin [20/2] he suffices with the latter pasuk:
Whenever a person violates a prohibition punishable by execution by the court under duress, the court should not execute him. Even in situations where the transgressor was commanded to sacrifice his life and not transgress, if he sinned under duress, although he desecrated God's name, he should not be executed. This is derived from Deuteronomy 22:26: "To the maiden, you should not do anything." This verse is a warning to the court not to punish a person who transgresses under duress.
Why is one pasuk enough here?
Why is one pasuk enough here?
