R’Akiva and R’Eliezer vigorously dispute the conditions under which slaughter is permissible on the Sabbath, At one point R’Eliezer lashes out: “Akiva! You have answered me irreverently in a matter of slaughter– through slaughter shall be his death!”
R’Akiva explains that his answer had been an attempt to remind R’Eliezer that he himself had taught Akiva the law Eliezer was now apparently refuting. “He held that it was not proper for him to openly correct his teacher.”
The gemara continues, seeking to understand why R’Eliezer holds that sprinkling the Pesach offering on Shabbes is a problem. Rav Yehudah rules in favor of R’Akiva. In the argument R Eliezer curses R Akiva "“Akiva! You have answered me irreverently in a matter involving slaughter, through slaughter shall be your death” leading us to examine truth and its consequences in Talmud.
