Shalom,
I often find you site very helpful, particularly the explanations of the Tosafot.
I'd like to point out an error that you have for Berkahot 21b:
>>(e) Question (Rav Ada bar Ahavah): What is the source that an individual does not say Kedushah?
(f) Answer: We learn from "v'Nikdashti b'Soch Bnei Yisrael" -- every matter of Kedushah needs 10 men.
(g) Question: How do we learn this from the verse?
(h) Answer (Ravnai, brother of R. Chiya bar Aba): We learn from a Gezeirah Shavah "Toch-Toch":
1. It says here "v'Nikdashti b'Soch Bnei Yisrael," like it says about the Meraglim "Hibadlu mi'Toch ha'Edah ha'Zos";
2. Just like there, there were 10 (evil Meraglim), also here there must be 10 (Yisre'elim).<<
The problem is that the verse cited is about Korah and his cohorts and not the meraglim), and we don't know that they were 10. Rather, you need another gezera shava, edah-edah, with the edah of the meraglim, and you'll find the complete double-gezera shava in Megilla 23b. So here, in Berakhot, you should say that this verse is about Korah and his cohorts, and then add a comment that you know an edah has 10 from another verse, which is about the meraglim.
Thanks for your attention.
You are correct. Thanks for pointing this out. We will change the outline for Berachos 21b 3:h:1 to read
1. It says here "v'Nikdashti b'Soch Bnei Yisrael," like it says about Adas Korach "mi'Toch ha'Edah". We learn "Edah-Edah" from "la'Edah ha'Ra'ah ha'Zos", which refers to the Meraglim;
