Shevuot 5 - May 6, 8 Iyar

Today's daf is sponsored by Gabrielle Altman in honor of her husband, Daniel Altman, on his fourth completion of the Daf Yomi cycle. "May he continue teaching the Daf and inspiring people to learn the Daf for decades to come, in good health." When Rabbi Yehuda Hanasi wrote in the Mishna "Shevuot there are two that are four," was it his own opinion also or was he just quoting Rabbi Akiva's opinion but he actually doesn't hold that way? At first, they tried to prove it was Rebbi's own opinion, but this option failed and they adopted the other explanation. Rebbi holds that "v'neelam" means he knew and then forgot - does that word necessarily translate in that manner? By a woman who is a sotah, that word is mentioned and it doesn't mean that.   The Mishna states "Taking things out on Shabbat there are two that are four" - this is different from the Mishna in Shabbat which lists two that are four inside and two that are four outside. What are the mishnayot in each place referring to and why are they referring to different things?  The Mishna states "Leprous marks two that are four" - does the Mishna not accord with Rabbi Akiva's position?
