Sorry that I missed a few days, although it's 5 Elul and I'm up to Halacha 5, so I'm still on target.
This Halacha deals with the Scapegoat that was a central part of the Yom Kippur service in the Temple.
הִלְכּוֹת תְּשׁוּבָה פֵּרֶק א, הלכה ה
|שָׂעִיר הַמִּשְׁתַּלֵּחַ--לְפִי שְׁהוּא כַּפָּרָה לְכָל יִשְׂרָאֵל, כּוֹהֵן גָּדוֹל מִתְוַדֶּה עָלָיו עַל לְשׁוֹן כָּל יִשְׂרָאֵל: שֶׁנֶּאֱמָר "וְהִתְוַדָּה עָלָיו אֶת-כָּל-עֲוֹנֹת בְּנֵי יִשְׂרָאֵל" (ויקרא טז,כא).|
Hilchot Tshuva, Chapter 1, Halacha 5
|The “Scapegoat” – as it serves as an atonement for all the Jewish people, the Cohen Gadol confesses over it using a language for all Israel, as it is written: “And he shall confess over it for all the sins of the Children of Israel” (Vayikra 15:21)|
