The Mitzvah of Viduy - he confesses on Erev Yom Kipur when it gets dark [after accepting Kedushas Yom Kipur], but Chachamim said that he should confess before he gets engrossed in food and drink;

Even though he confessed in Ma'ariv, he must confess in Shacharis. Even though he confessed in Shacharis, he must confess in Musaf. Even though he confessed in Musaf, he must confess in Minchah. Even though he confessed in Minchah, he must confess in Ne'ilah, for the entire day is Kosher for Viduy [and the more one confesses, the better];

How does he confess? R. Berachiyah citing R. Ba bar Binah says, "my Master! I sinned and did evil. I stood with bad intent and went in the far path [from You]. Like I did, I will not do. May it be Your will to atone for all my Pesha'im, pardon me for all my Aveiros, and forgive all my Chata'im.''

(Beraisa): He must detail his deeds (mention all his Aveiros). R. Yehudah ben Beseira says so. R. Akiva says, he need not detail his deeds.

What is R. Yehudah's reason? "Ana Chata ha'Am ha'Zeh Chata'ah Gedolah va'Ya'asu Lahem Elohei Zahav.''

How does R. Akiva explain this? Who caused them [to do this sin? Moshe hinted that Hash-m say] "I did, for I gave to them much silver and gold.'' Why [is this a cause of sin]? A donkey goes wild only when it has a basket of carobs (it likes them very much).

It says "Mikveh Yisrael Hash-m...'' - just like a Mikveh is Metaher Temei'im, so Hash-m is Metaher Yisrael, and so it says "v'Zarakti Aleichem Mayim Tehorim u'T'hartem mi'Kol Tum'oseichem umi'Kol Giluleichem Etaher Eschem.''
