From My Jewish Learning:
It’s difficult to imagine two holidays more different than Yom Kippur and Purim. Yom Kippur is the Day of Atonement, a somber occasion for contemplating one’s misdeeds in the previous year and seeking to right those wrongs. Purim is a day set aside for ecstatically celebrating the Jewish people’s escape from a genocidal maniac. Yom Kippur is for fasting, while Purim is for feasting. Yom Kippur is solemn, Purim is raucous. Yom Kippur is full of restrictions, while Purim has none. On Yom Kippur Jews consider their own certain mortality, on Purim they celebrate unlikely escape from the clutches of death. On Yom Kippur, Jews confront themselves in the hopes of entering the new year with a clean slate. On Purim, they celebrate a successful confrontation with their evil attackers.
And yet, since the rabbinic period, Jewish tradition has repeatedly linked these two holidays, arguing that they are actually opposite sides of a single coin.
The Vilna Gaon wrote: here is a rule for every Yom Tov, that it is half for God and half for you. Two holidays are exceptions to this rule. Yom Kippur is entirely for God, and Purim is entirely for you. But...there is no exception from the rule. For Yom Kippurim is Yom K-("like")-Purim. Meaning: both together make up one holy time. And in this holy time are included Purim and Yom Kippur, and it stands as half for God and half for you.
(ז) וַיֹּאמְר֞וּ אִ֣ישׁ אֶל־רֵעֵ֗הוּ לְכוּ֙ וְנַפִּ֣ילָה גֽוֹרָל֔וֹת וְנֵ֣דְעָ֔ה בְּשֶׁלְּמִ֛י הָרָעָ֥ה הַזֹּ֖את לָ֑נוּ וַיַּפִּ֙לוּ֙ גּֽוֹרָל֔וֹת וַיִּפֹּ֥ל הַגּוֹרָ֖ל עַל־יוֹנָֽה׃
(7) Those aboardbThose aboard Heb. “They.” said to one another, “Let us cast lots and find out on whose account this misfortune has come upon us.” They cast lots and the lot fell on Jonah.
(ז) בַּחֹ֤דֶשׁ הָרִאשׁוֹן֙ הוּא־חֹ֣דֶשׁ נִיסָ֔ן בִּשְׁנַת֙ שְׁתֵּ֣ים עֶשְׂרֵ֔ה לַמֶּ֖לֶךְ אֲחַשְׁוֵר֑וֹשׁ הִפִּ֣יל פּוּר֩ ה֨וּא הַגּוֹרָ֜ל לִפְנֵ֣י הָמָ֗ן מִיּ֧וֹם ׀ לְי֛וֹם וּמֵחֹ֛דֶשׁ לְחֹ֥דֶשׁ שְׁנֵים־עָשָׂ֖ר הוּא־חֹ֥דֶשׁ אֲדָֽר׃ {ס}
(7) In the first month, that is, the month of Nisan, in the twelfth year of King Ahasuerus, pur—which means “the lot”—was cast before Haman concerning every day and every month, [until it fell on] the twelfth month, that is, the month of Adar.
(א) ונתן אהרן על שני השעירם גרלות. מַעֲמִיד אֶחָד לְיָמִין וְאֶחָד לִשְׂמֹאל, וְנוֹתֵן שְׁתֵּי יָדָיו בַּקַּלְפִּי, וְנוֹטֵל גּוֹרָל בְּיָמִין וַחֲבֵרוֹ בִּשְׂמֹאל וְנוֹתֵן עֲלֵיהֶם, אֶת שֶׁכָּתוּב בּוֹ "לַשֵּׁם" הוּא לַשֵּׁם, וְאֶת שֶׁכָּתוּב בּוֹ "לַעֲזָאזֵל" מִשְׁתַּלֵּחַ לַעֲזָאזֵל (יומא ל"ט):
(1) השעירים גרלותשני על אהרן ונתן AND AARON SHALL CAST LOTS UPON THE TWO GOATS — He places one goat at his right and the other at his left. He then puts both his hands into an urn and takes one lot in his right hand and the other in his left. These he places upon them (the goats; i.e. one upon each of them). The goat upon which there fell that lot bearing the inscription 'לה, "For the Lord" was destined for the Lord, and that upon which there fell that lot bearing the inscription "For Azazel" was afterwards sent forth to the Azazel (Yoma 39a).
(ט) וַיֹּ֥אמֶר אֲלֵיהֶ֖ם עִבְרִ֣י אָנֹ֑כִי וְאֶת־יְהֹוָ֞ה אֱלֹהֵ֤י הַשָּׁמַ֙יִם֙ אֲנִ֣י יָרֵ֔א אֲשֶׁר־עָשָׂ֥ה אֶת־הַיָּ֖ם וְאֶת־הַיַּבָּשָֽׁה׃
(9) “I am a Hebrew,” he replied. “I worship the ETERNAL, the God of Heaven, who made both sea and land.”
(י) לֹא־הִגִּ֣ידָה אֶסְתֵּ֔ר אֶת־עַמָּ֖הּ וְאֶת־מֽוֹלַדְתָּ֑הּ כִּ֧י מׇרְדֳּכַ֛י צִוָּ֥ה עָלֶ֖יהָ אֲשֶׁ֥ר לֹא־תַגִּֽיד׃ {ס}
(10) Esther did not reveal her people or her kindred, for Mordecai had told her not to reveal it.
(ג) וַיָּ֤קׇם יוֹנָה֙ לִבְרֹ֣חַ תַּרְשִׁ֔ישָׁה מִלִּפְנֵ֖י יְהֹוָ֑ה וַיֵּ֨רֶד יָפ֜וֹ וַיִּמְצָ֥א אֳנִיָּ֣ה ׀ בָּאָ֣ה תַרְשִׁ֗ישׁ וַיִּתֵּ֨ן שְׂכָרָ֜הּ וַיֵּ֤רֶד בָּהּ֙ לָב֤וֹא עִמָּהֶם֙ תַּרְשִׁ֔ישָׁה מִלִּפְנֵ֖י יְהֹוָֽה׃
(3) Jonah, however, started out to flee to Tarshish from GOD’s service. He went down to Joppa and found a ship going to Tarshish. He paid the fare and went aboard to sail with the others to Tarshish, away from GOD’s service.
(א) וַיְהִ֧י דְבַר־יְהֹוָ֛ה אֶל־יוֹנָ֖ה שֵׁנִ֥ית לֵאמֹֽר׃ (ב) ק֛וּם לֵ֥ךְ אֶל־נִֽינְוֵ֖ה הָעִ֣יר הַגְּדוֹלָ֑ה וּקְרָ֤א אֵלֶ֙יהָ֙ אֶת־הַקְּרִיאָ֔ה אֲשֶׁ֥ר אָנֹכִ֖י דֹּבֵ֥ר אֵלֶֽיךָ׃ (ג) וַיָּ֣קׇם יוֹנָ֗ה וַיֵּ֛לֶךְ אֶל־נִֽינְוֵ֖ה כִּדְבַ֣ר יְהֹוָ֑ה וְנִֽינְוֵ֗ה הָיְתָ֤ה עִיר־גְּדוֹלָה֙ לֵֽאלֹהִ֔ים מַהֲלַ֖ךְ שְׁלֹ֥שֶׁת יָמִֽים׃
(1) The word of GOD came to Jonah a second time: (2) “Go at once to Nineveh, that great city, and proclaim to it what I tell you.” (3) Jonah went at once to Nineveh in accordance with GOD’s command.

(13) Mordecai had this message delivered to Esther: “Do not imagine that you, of all the Jews, will escape with your life by being in the king’s palace. (14) On the contrary, if you keep silent in this crisis, relief and deliverance will come to the Jews from another quarter, while you and your father’s house will perish. And who knows, perhaps you have attained to royal position for just such a crisis.”
(ה) וַֽיַּאֲמִ֛ינוּ אַנְשֵׁ֥י נִֽינְוֵ֖ה בֵּֽאלֹהִ֑ים וַיִּקְרְאוּ־צוֹם֙ וַיִּלְבְּשׁ֣וּ שַׂקִּ֔ים מִגְּדוֹלָ֖ם וְעַד־קְטַנָּֽם׃
(5) The people of Nineveh believed God. They proclaimed a fast, and great and small alike put on sackcloth.
(טז) לֵךְ֩ כְּנ֨וֹס אֶת־כׇּל־הַיְּהוּדִ֜ים הַֽנִּמְצְאִ֣ים בְּשׁוּשָׁ֗ן וְצ֣וּמוּ עָ֠לַ֠י וְאַל־תֹּאכְל֨וּ וְאַל־תִּשְׁתּ֜וּ שְׁלֹ֤שֶׁת יָמִים֙ לַ֣יְלָה וָי֔וֹם גַּם־אֲנִ֥י וְנַעֲרֹתַ֖י אָצ֣וּם כֵּ֑ן וּבְכֵ֞ן אָב֤וֹא אֶל־הַמֶּ֙לֶךְ֙ אֲשֶׁ֣ר לֹֽא־כַדָּ֔ת וְכַאֲשֶׁ֥ר אָבַ֖דְתִּי אָבָֽדְתִּי׃
(16) “Go, assemble all the Jews who live in Shushan, and fast in my behalf; do not eat or drink for three days, night or day. I and my maidens will observe the same fast. Then I shall go to the king, though it is contrary to the law; and if I am to perish, I shall perish!”
(כד) כִּי֩ הָמָ֨ן בֶּֽן־הַמְּדָ֜תָא הָֽאֲגָגִ֗י צֹרֵר֙ כׇּל־הַיְּהוּדִ֔ים חָשַׁ֥ב עַל־הַיְּהוּדִ֖ים לְאַבְּדָ֑ם וְהִפִּ֥ל פּוּר֙ ה֣וּא הַגּוֹרָ֔ל לְהֻמָּ֖ם וּֽלְאַבְּדָֽם׃ (כה) וּבְבֹאָהּ֮ לִפְנֵ֣י הַמֶּ֒לֶךְ֒ אָמַ֣ר עִם־הַסֵּ֔פֶר יָשׁ֞וּב מַחֲשַׁבְתּ֧וֹ הָרָעָ֛ה אֲשֶׁר־חָשַׁ֥ב עַל־הַיְּהוּדִ֖ים עַל־רֹאשׁ֑וֹ וְתָל֥וּ אֹת֛וֹ וְאֶת־בָּנָ֖יו עַל־הָעֵֽץ׃
(24) For Haman son of Hammedatha the Agagite, the foe of all the Jews, had plotted to destroy the Jews, and had cast pur—that is, the lot—with intent to crush and exterminate them. (25) But when [Esther] came before the king, he commanded: bMeaning of Heb. uncertain.“With the promulgation of this decree,-b let the evil plot, which he devised against the Jews, recoil on his own head!” So they impaled him and his sons on the stake.
(י) וַיַּ֤רְא הָֽאֱלֹהִים֙ אֶֽת־מַ֣עֲשֵׂיהֶ֔ם כִּי־שָׁ֖בוּ מִדַּרְכָּ֣ם הָרָעָ֑ה וַיִּנָּ֣חֶם הָאֱלֹהִ֗ים עַל־הָרָעָ֛ה אֲשֶׁר־דִּבֶּ֥ר לַעֲשׂוֹת־לָהֶ֖ם וְלֹ֥א עָשָֽׂה׃
(10) God saw what they did, how they were turning back from their evil ways. And God renounced the punishment that had been planned for them, and did not carry it out.
(א) וַיֵּ֥רַע אֶל־יוֹנָ֖ה רָעָ֣ה גְדוֹלָ֑ה וַיִּ֖חַר לֽוֹ׃ (ב) וַיִּתְפַּלֵּ֨ל אֶל־יְהֹוָ֜ה וַיֹּאמַ֗ר אָנָּ֤ה יְהֹוָה֙ הֲלוֹא־זֶ֣ה דְבָרִ֗י עַד־הֱיוֹתִי֙ עַל־אַדְמָתִ֔י עַל־כֵּ֥ן קִדַּ֖מְתִּי לִבְרֹ֣חַ תַּרְשִׁ֑ישָׁה כִּ֣י יָדַ֗עְתִּי כִּ֤י אַתָּה֙ אֵֽל־חַנּ֣וּן וְרַח֔וּם אֶ֤רֶךְ אַפַּ֙יִם֙ וְרַב־חֶ֔סֶד וְנִחָ֖ם עַל־הָרָעָֽה׃
(1) This displeased Jonah greatly, and he was grieved. (2) He prayed to GOD, saying, “O ETERNAL One ! Isn’t this just what I said when I was still in my own country? That is why I fled beforehand to Tarshish. For I know that You are a compassionate and gracious God, slow to anger, abounding in kindness, renouncing punishment.
