This moment of atonement, when a bad decision in the past was left behind and a new path forward made clear, set the precedent for what Yom Kippur is all about.
How might this understanding of Yom Kippur influence our experience of the holiday?
Why might it matter that both Purim and Yom Kippur celebrate a second chance at accepting the Torah?
Think of a time when you had a second chance to make something right. How was it different from the first time? What did you learn in the process?
...עַצְמוֹ שֶׁל יוֹם הַכִּפּוּרִים מְכַפֵּר לַשָּׁבִים שֶׁנֶּאֱמַר (ויקרא טז:ל) "כִּי בַיּוֹם הַזֶּה יְכַפֵּר עֲלֵיכֶם"...
...Yom Kippur itself atones for those who return, as it says (Lev. 16:30), “For with this day you will atone on yourselves…”.

Jacob, God’s own allotment.
יום הכפורים – משום דאית ביה סליחה ומחילה, יום שניתנו בו לוחות האחרונות.
Yom HaKippurim – For on this day there is forgiveness and pardoning; it is the day on which we received the Second Tablets.
וְכִפֶּר עַל הַקֹּדֶשׁ מִטֻּמְאֹת בְּנֵי יִשְׂרָאֵל וּמִפִּשְׁעֵיהֶם לְכָל חַטֹּאתָם וְכֵן יַעֲשֶׂה לְאֹהֶל מוֹעֵד הַשֹּׁכֵן אִתָּם בְּתוֹךְ טֻמְאֹתָם.
And he will atone over the holies from the impurities of the Children of Israel and their iniquities, for all their mistakes, and so shall he do for the Tent of Meeting which dwells with you amongst your impurity.
אכפרה פניו I WILL APPEASE HIM — I will remove his anger. Similarly, (Isaiah 28:18) "and your covenant with death shall be annulled (וכפר)”;Thou shalt not be able to put it away (וכפרה”. I am of the opinion that wherever the verb כפר is used in association with iniquity and sin and in association with anger (פנים), it always signifies wiping away, removing. It is an Aramaic expression occurring frequently in the Talmud: “He wiped his hand off (כפר ידיה)”, and (Gittin 56a) ‘‘he wants to wipe (לכפורי) his hands off on this man” . In Biblical Hebrew, also, the bowls of the Sanctuary are called, (Ezra 1:10) "כפורי of gold” — and they are so called because the priest wiped his hands on them — on the rim of the bowl (Zevachim 93b).
