On our daf we find that Shabbos is so stringent that even a מצוה מת does not override it.
Rav Simi bar Ashi said: The Tanna who used the verse to teach us that Beis Din may not perform an execution on Shabbos did not need the verse because otherwise we would have thought that a positive commandment overrides a prohibition even though it involves kares.
יד וּשְׁמַרְתֶּם, אֶת-הַשַּׁבָּת, כִּי קֹדֶשׁ הִוא, לָכֶם; מְחַלְלֶיהָ, מוֹת יוּמָת--כִּי כָּל-הָעֹשֶׂה בָהּ מְלָאכָה, וְנִכְרְתָה הַנֶּפֶשׁ הַהִוא מִקֶּרֶב עַמֶּיהָ.
14 Ye shall keep the sabbath therefore, for it is holy unto you; everyone that profaneth it shall surely be put to death; for whosoever doeth any work therein, that soul shall be cut off from among his people.
Ex 31:14
“Everyone who profanes it shall surely be put to death” ?
This applies to other prohibited labors, except for court-imposed capital punishment.
We explore court imposed capital punishment in the writings of modern legal experts well versed in both Talmud and secular law.
How does the Torah’s idea of capital punishment line up with modern legal mistake when putting innocent people to death?
