Question (Part 1): Seeing as there was no warning, on what basis was Yo'av sentenced to death?

Suggested Answer: Perhaps it was because he was a Chaver, and a Chaver does not require Hasra'ah?

Refutal: The fact is that in this instance, Yo'av could not be considered a Chaver, since David treated him as a Mored be'Malchus, in which case he had the Din of a regular Shogeg.

Answer: The actual death-sentence was for rebelling against the king (Moreid be'Malchus), which does not require Hasra'ah.

Statement: We find this collection of Amora'im a number of times in Shas.

Implied Question: Then why, at the end of 'Eilu Metzi'os, did Rava state 'Like Rav Sechorah, who taught me the meaning of 'Zuhama Lis'teron' (a kind of ladle), as if that was all that he ever taught im?

Answer #1: That was indeed the only thing that he (Rav Sechorah) ever taught him off his own bat.

Answer #2: Alternatively, what Rava means is that even if this was the only thing he ever learned from him, that would suffice to call him his Rebbe... .

Answer #3: Or perhaps at that moment, that was all he had learned from him (and the rest he learned only later).

Explanation #1 (Rashi): Rashi explains that the test was to ascertain whether or not it was the blood of Nidus or not.

Explanation #2: Rabeinu Tam however, maintains that it applies even to blood that is definitely Dam Nidus, even though it is Metamei both wet and dry, since it is not removed via the seven 'dyes', it is Batel and the garment is Taor ...

Proof: ... like the Beraisa cited by R. Chiya - 'If a garment contains the blood of Vaday Nidus, one washes it with the seven (specified) dyes and negates it (the blood).

Clarification: According to the opinion in Yoma, 60a who hold that the Torah only writes Chukah with regard to the things that were performed inside (the Kodesh Kodshim) wearing the white garments, it is not speaking about the things that were performed outside, wearing the golden garments.

Question #1: Why does the Gemara not also include 'Seider B'rachos', seeing as the Mishnah in the last Perek of Rosh Hashanah, Daf 32a says about them 'Seider B'rachos Avos, u'Gevuros u'Kedushas Hashem'?

Question #2: And by the same token, why does it not include the order of the Teki'os (as stated in the Mishnah there (on Daf 33b)?
