Reply To: Techeiles 🔵❎🐌☑️🐟

“PAA, and sam2 about the lashon of chut lashon yachid and shittas tosfos, the tosfos harosh yevamos 5b also uses the lashon chut shel techeiles to refer to the mitzvah of techeiles even though he holds like tosfos.”

I don’t know if this is a good raya. No one ever suggested that the rishonim who held of four strings never saw this gemara. Obviusly they either held it was lav davka or they had some other way to get out of it. So proving that the Rosh thought that it was lav davka doesn’t really accomplish anything. The point that was being pointed out is that the gemara taken at face value seems to say that there’s only one string of techeiles. The Torah Temima in fact brings this gemara as support for the Rambam’s shitta (although he does explain that Rashi would interpret it differently).
