Beginning from where must a person read the Megilla in order to fulfill his obligation? Rabbi Meir says: He must read all of it. Rabbi Yehuda says: He need read only from “There was a certain Jew” (Esther 2:5). Rabbi Yosei says: From “After these things” (Esther 3:1).
§ The mishna teaches that three Sages disagree about the question: Beginning from where must a person read the Megilla in order to fulfill his obligation? It is taught in a baraita that there is a fourth opinion as well: Rabbi Shimon bar Yoḥai says: One must start to read from “On that night” (Esther 6:1). Rabbi Yoḥanan said: And all of these tanna’im, in arriving at their respective opinions, were expounding the same verse. As it is stated: “Then Esther the queen, the daughter of Abihail, and Mordecai the Jew, wrote about all the acts of power to confirm this second letter of Purim” (Esther 9:29). The one who said that the Megilla must be read in its entirety interprets “acts of power” as referring to the power of Ahasuerus, and so the Megilla must be read from the beginning, where the power of Ahasuerus is recounted. And the one who said that it needs to be read from “There was a certain Jew” explains that “acts of power” is referring to the power of Mordecai. And the one who said that it needs to be read from “After these things” maintains that “acts of power” is referring to the power of Haman. And the one who said that it needs to be read from “On that night” understands that the expression is referring to the power of the miracle, which began on that night when Ahasuerus could not sleep, and therefore one must begin reading the Megilla from there.
א"ר חלבו אמר רב חמא בר גוריא אמר רב הלכה כדברי האומר כולה
Rabbi Ḥelbo said that Rav Ḥama bar Gurya said that Rav said: The halakha is in accordance with the statement of the one who says that the Megilla must be read in its entirety.
Rabbi Ya’akov bar Idi said that Rabbi Yoḥanan said: In the case of a dispute between Rabbi Meir and Rabbi Yehuda, the halakha is in accordance with the opinion of Rabbi Yehuda; in the case of a dispute between Rabbi Yehuda and Rabbi Yosei, the halakha is in accordance with the opinion of Rabbi Yosei; and, needless to say, in the case of a dispute between Rabbi Meir and Rabbi Yosei, the halakha is in accordance with the opinion of Rabbi Yosei. As now, if in disputes with Rabbi Yehuda, the opinion of Rabbi Meir is not accepted as law, need it be stated that in disputes with Rabbi Yosei, Rabbi Meir’s opinion is rejected? Rabbi Yehuda’s opinion is not accepted in disputes with Rabbi Yosei.
רבי אחא בר חנינא גלוי וידוע לפני מי שאמר והיה העולם שאין בדורו של רבי מאיר כמותו ומפני מה לא קבעו הלכה כמותו שלא יכלו חביריו לעמוד על סוף דעתו
Rabbi Aḥa bar Ḥanina said: It is revealed and known before the One Who spoke and the world came into being that in the generation of Rabbi Meir there was no one of the Sages who is his equal. Why then didn’t the Sages establish the halakha in accordance with his opinion? It is because his colleagues were unable to ascertain the profundity of his opinion.

(1) You are children of the LORD your God. You shall not gash yourselves or shave the front of your heads because of the dead.
בנים אתם ליקוק אלקיכם בזמן שאתם נוהגים מנהג בנים אתם קרוים בנים אין אתם נוהגים מנהג בנים אין אתם קרוים בנים דברי ר' יהודה רבי מאיר אומר בין כך ובין כך אתם קרוים בנים שנאמר (ירמיהו ד, כב) בנים סכלים המה ואומר (דברים לב, כ) בנים לא אמון בם ואומר (ישעיהו א, ד) זרע מרעים בנים משחיתים ואומר (הושע ב, א) והיה במקום אשר יאמר להם לא עמי אתם יאמר להם בני אל חי מאי ואומר וכי תימא סכלי הוא דמקרי בני כי לית בהו הימנותייהו לא מיקרו בני ת"ש ואומר בנים לא אמון בם וכי תימא כי לית בהו הימנותא הוא דמיקרו בנים כי פלחו לעבודת כוכבים לא מיקרו בנים ת"ש ואומר זרע מרעים בנים משחיתים וכ"ת בנים משחיתים הוא דמיקרו בני מעלייא לא מיקרו ת"ש ואומר והיה במקום אשר יאמר להם לא עמי אתם יאמר להם בני אל חי
The verse: “You are the sons to the Lord your God,” indicates that when you act like sons and cleave to the Holy One, Blessed be He, you are called sons, but when you do not act like sons you are not called sons. This is the statement of Rabbi Yehuda. And Rabbi Meir says: Either way you are still called sons, as it is stated: “They are foolish sons” (Jeremiah 4:22). And it also states: “Sons in whom there is no faithfulness” (Deuteronomy 32:20). And it states: “A seed of evildoers, sons who deal corruptly” (Isaiah 1:4). And it states: “And it shall come to pass that, instead of what was said to them: You are not My people, it shall be said to them: Sons of the living God” (Hosea 2:1). The Gemara asks: Why is it necessary to cite these additional proofs introduced by the phrase: And it states? All these verses apparently make the same point. The Gemara explains why all the quotes are necessary. And if you would say: Granted, when they are foolish they are still called sons, as the verse states: “Foolish sons,” but when they do not have faithfulness they are not called sons; therefore, come and hear another verse. And that verse states: “Sons in whom there is no faithfulness.” And if you would say: It is when they do not have faithfulness that they are called sons, as stated, but when they worship idols they are not called sons anymore; therefore, come and hear: And the verse states: “A seed of evildoers, sons who deal corruptly,” which alludes to the corruption of idol worship. And if you would say that although they are called “sons who deal corruptly,” they are no longer called full-fledged sons of God once they have sinned, come and hear: And the verse states: “And it shall come to pass that, instead of what was said to them: You are not My people, it shall be said to them: Sons of the living God.” This verse indicates that when the Jews repent they are again called full-fledged sons of God.
ואף על גב דרבי מאיר ורבי יהודה הלכה כר"י הכא ר"מ קראי קא דייקי
Responsa of the Rashba 1:194, 1:242
And even though when there is a dispute between Rebbe Meir and Rebbe Yehudah the halachah follows Rebbe Yehuda, here [we follow] Rebbe Meir based on his use of the verses.
Shlomo ben Avraham ibn Adret (Rashba) was a Spanish rabbi, Talmudic commentator, posek and community leader in the 14th century. He lived his entire life in Barcelona. He is considered the most outstanding student of the Ramban, and continued his approach in Talmudic exposition, authoring chiddushim (Talmudic novellae) on many tractates which remain mainstays of Torah study to this day. His yeshiva drew exceptional students from throughout the Jewish world, including quite a number from Germany. He functioned as chief rabbi of Spain and wrote over one thousand responsa to individuals and communities throughout the Jewish world. He was involved in opposition to Rambam's philosophical writings and prohibited the study of philosophy under the age of 25. He also defended Judaism to Christian and Moslem polemicists, and vigorously opposed the activity of R. Avraham Abulafia. He vigorously defended his work, Torat HaBayit, against R. Aharon Halevy's often strident comments.

(טז) כָּל אַהֲבָה שֶׁהִיא תְלוּיָה בְדָבָר, בָּטֵל דָּבָר, בְּטֵלָה אַהֲבָה. וְשֶׁאֵינָהּ תְּלוּיָה בְדָבָר, אֵינָהּ בְּטֵלָה לְעוֹלָם. אֵיזוֹ הִיא אַהֲבָה הַתְּלוּיָה בְדָבָר, זוֹ אַהֲבַת אַמְנוֹן וְתָמָר. וְשֶׁאֵינָהּ תְּלוּיָה בְדָבָר, זוֹ אַהֲבַת דָּוִד וִיהוֹנָתָן:
(16) Any love that is dependent on something, when that thing perishes, the love perishes. But [a love] that is not dependent on something, does not ever perish. What's [an example of] a love that is dependent on something? That's the love of Amnon and Tamar. And [a love] that is not dependent on something? That's the love of David and Jonathan.
Rava said: A person is obligated to become intoxicated with wine on Purim until he is so intoxicated that he does not know how to distinguish between cursed is Haman and blessed is Mordecai.
One should rather spend more money on gifts to the poor than on his Purim banquet and presents to his friends. No joy is greater and more glorious than the joy of gladdening the hearts of the poor, the orphans, the widows, and the strangers. He who gladdens the heart of these unhappy people imitates God, as it is written: "I am … to revive the spirit of the humble, and to put heart into the crushed" (Isaiah 57:15).
Rabbi Pinchas Friedman

שאל טורנוסרופוס הרשע את ר"ע אם אלקיכם אוהב עניים הוא מפני מה אינו מפרנסם אמר לו כדי שניצול אנו בהן מדינה של גיהנם אמר לו [אדרבה] זו שמחייבתן לגיהנם אמשול לך משל למה הדבר דומה למלך בשר ודם שכעס על עבדו וחבשו בבית האסורין וצוה עליו שלא להאכילו ושלא להשקותו והלך אדם אחד והאכילו והשקהו כששמע המלך לא כועס עליו ואתם קרוין עבדים שנאמר (ויקרא כה, נה) כי לי בני ישראל עבדים אמר לו ר"ע אמשול לך משל למה הדבר דומה למלך בשר ודם שכעס על בנו וחבשו בבית האסורין וצוה עליו שלא להאכילו ושלא להשקותו והלך אדם אחד והאכילו והשקהו כששמע המלך לא דורון משגר לו ואנן קרוין בנים דכתיב (דברים יד, א) בנים אתם ליקוק אלקיכם
§ It is taught in a baraita: Rabbi Meir would say: An opponent may bring an argument against you and say to you: If your God loves the poor, for what reason does He not support them Himself? In such a case, say to him: He commands us to act as His agents in sustaining the poor, so that through them we will be credited with the performance of mitzvot and therefore be saved from the judgment of Gehenna. And this is the question that Turnus Rufus the wicked asked Rabbi Akiva: If your God loves the poor, for what reason does He not support them Himself? Rabbi Akiva said to him: He commands us to sustain the poor, so that through them and the charity we give them we will be saved from the judgment of Gehenna. Turnus Rufus said to Rabbi Akiva: On the contrary, it is this charity which condemns you, the Jewish people, to Gehenna because you give it. I will illustrate this to you with a parable. To what is this matter comparable? It is comparable to a king of flesh and blood who was angry with his slave and put him in prison and ordered that he should not be fed or given to drink. And one person went ahead and fed him and gave him to drink. If the king heard about this, would he not be angry with that person? And you, after all, are called slaves, as it is stated: “For the children of Israel are slaves to Me” (Leviticus 25:55). If God decreed that a certain person should be impoverished, one who gives him charity defies the will of God. Rabbi Akiva said to Turnus Rufus: I will illustrate the opposite to you with a different parable. To what is this matter comparable? It is comparable to a king of flesh and blood who was angry with his son and put him in prison and ordered that he should not be fed or given to drink. And one person went ahead and fed him and gave him to drink. If the king heard about this once his anger abated, would he not react by sending that person a gift? And we are called sons, as it is written: “You are sons of the Lord your God” (Deuteronomy 14:1).
