may argue for or against the defendant, but in capital cases, all may argue in favor of the defendant, but not against the defendant. The Gemara asked whether the reference to "all" in this Mishnah included even the witnesses. Rabbi Jose son of Rabbi Judah and the Rabbis disagreed to some degree. The Gemara read the words of , "But one witness shall not testify against any person," to indicate that a witness cannot participate in a trial — either for acquittal or condemnation — beyond providing testimony. Rabbi Jose son of Rabbi Judah taught that a witness could argue for acquittal, but not for condemnation. Rav Papa taught that the word "all" means to include not the witnesses, but the Rabbinical students who attended trials, and thus was not inconsistent with the views of Rabbi Jose son of Rabbi Judah or of the Rabbis. The Gemara explained the reasoning of Rabbi Jose son of Rabbi Judah for his view that witnesses may argue in favor of the accused as follows: says, "But one witness shall not testify against any person that he die." Hence, according to the reasoning of Rabbi Jose son of Rabbi Judah, only "so that he die" could the witness not argue, but the witness could argue for acquittal. And Resh Lakish explained the reasoning of the Rabbis forbidding a witness to argue in favor of the accused as follows: The Rabbis reasoned that if a witness could argue the case, then the witness might seem personally concerned in his testimony (for a witness contradicted by subsequent witnesses could be subject to execution for testifying falsely). The Gemara then asked how the Rabbis interpreted the words, "so that he die" (which seems to indicate that the witness may not argue only when it leads to death). The Gemara explained that the Rabbis read those words to apply to the Rabbinical students (constraining the students not to argue for condemnation). A Baraita taught that they did not listen to a witnesses who asked to make a statement in the defendant's favor, because says, "But one witness shall not testify." And they did not listen to a Rabbinical student who asked to argue a point to the defendant's disadvantage, because says, "One shall not testify against any person that he die" (but a student could do so for acquittal). The Gemara cited the Torah's requirement for corroborating witnesses
