בשנייה זכור וכו': איתמר פורים שחל להיות בע"ש רב אמר מקדימין פרשת זכור ושמואל אמר מאחרין
§ The mishna states: On the second Shabbat of Adar, the Shabbat prior to Purim, they read the portion of “Remember [zakhor] what Amalek did” (Deuteronomy 25:17–19). The portion of Zakhor is associated with Purim because according to tradition, Haman was a descendant of Amalek, and so the victory over him and his supporters was a victory against Amalek. With regard to this, an amoraic dispute was stated: With regard to when Purim occurs on a Friday, Rav said: The congregation advances the reading of the portion of Zakhor to the previous Shabbat. And Shmuel said: They defer it to the Shabbat following Purim.
(יז) זָכ֕וֹר אֵ֛ת אֲשֶׁר־עָשָׂ֥ה לְךָ֖ עֲמָלֵ֑ק בַּדֶּ֖רֶךְ בְּצֵאתְכֶ֥ם מִמִּצְרָֽיִם׃ (יח) אֲשֶׁ֨ר קָֽרְךָ֜ בַּדֶּ֗רֶךְ וַיְזַנֵּ֤ב בְּךָ֙ כָּל־הַנֶּחֱשָׁלִ֣ים אַֽחַרֶ֔יךָ וְאַתָּ֖ה עָיֵ֣ף וְיָגֵ֑עַ וְלֹ֥א יָרֵ֖א אֱלֹהִֽים׃
(17) Remember what Amalek did to you on your journey, after you left Egypt— (18) how, undeterred by fear of God, he surprised you on the march, when you were famished and weary, and cut down all the stragglers in your rear.
(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.
(כד) כִּי֩ הָמָ֨ן בֶּֽן־הַמְּדָ֜תָא הָֽאֲגָגִ֗י צֹרֵר֙ כָּל־הַיְּהוּדִ֔ים חָשַׁ֥ב עַל־הַיְּהוּדִ֖ים לְאַבְּדָ֑ם וְהִפִּ֥יל פּוּר֙ ה֣וּא הַגּוֹרָ֔ל לְהֻמָּ֖ם וּֽלְאַבְּדָֽם׃ (כה) וּבְבֹאָהּ֮ לִפְנֵ֣י הַמֶּלֶךְ֒ אָמַ֣ר עִם־הַסֵּ֔פֶר יָשׁ֞וּב מַחֲשַׁבְתּ֧וֹ הָרָעָ֛ה אֲשֶׁר־חָשַׁ֥ב עַל־הַיְּהוּדִ֖ים עַל־רֹאשׁ֑וֹ וְתָל֥וּ אֹת֛וֹ וְאֶת־בָּנָ֖יו עַל־הָעֵֽץ׃ (כו) עַל־כֵּ֡ן קָֽרְאוּ֩ לַיָּמִ֨ים הָאֵ֤לֶּה פוּרִים֙ עַל־שֵׁ֣ם הַפּ֔וּר עַל־כֵּ֕ן עַל־כָּל־דִּבְרֵ֖י הָאִגֶּ֣רֶת הַזֹּ֑את וּמָֽה־רָא֣וּ עַל־כָּ֔כָה וּמָ֥ה הִגִּ֖יעַ אֲלֵיהֶֽם׃
(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: “With the promulgation of this decree, 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. (26) For that reason these days were named Purim, after pur. In view, then, of all the instructions in the said letter and of what they had experienced in that matter and what had befallen them,
Yom Kippur or Yom Ki Pur?
(ח) וְנָתַ֧ן אַהֲרֹ֛ן עַל־שְׁנֵ֥י הַשְּׂעִירִ֖ם גּוֹרָל֑וֹת גּוֹרָ֤ל אֶחָד֙ לַיהוָ֔ה וְגוֹרָ֥ל אֶחָ֖ד לַעֲזָאזֵֽל׃
(8) and he shall place lots upon the two goats, one marked for the LORD and the other marked for Azazel.
(א) ונתן אהרן על שני השעירם גרלות. מַעֲמִיד אֶחָד לְיָמִין וְאֶחָד לִשְׂמֹאל, וְנוֹתֵן שְׁתֵּי יָדָיו בְּקַלְפִּי, וְנוֹטֵל גּוֹרָל בַּיָּמִין וַחֲבֵרוֹ בַּשְּׂמֹאל 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).
