The Origins of Birkat Hamazon
אָמַר רַב נַחְמָן: מֹשֶׁה תִּקֵּן לְיִשְׂרָאֵל בִּרְכַּת ״הַזָּן״ בְּשָׁעָה שֶׁיָּרַד לָהֶם מָן. יְהוֹשֻׁעַ תִּקֵּן לָהֶם בִּרְכַּת הָאָרֶץ כֵּיוָן שֶׁנִּכְנְסוּ לָאָרֶץ. דָּוִד וּשְׁלֹמֹה תִּקְּנוּ ״בּוֹנֵה יְרוּשָׁלַיִם״. דָּוִד תִּקֵּן ״עַל יִשְׂרָאֵל עַמֶּךָ וְעַל יְרוּשָׁלַיִם עִירֶךָ״, וּשְׁלֹמֹה תִּקֵּן ״עַל הַבַּיִת הַגָּדוֹל וְהַקָּדוֹשׁ״. ״הַטּוֹב וְהַמֵּטִיב״ בְּיַבְנֶה תִּקְּנוּהָ כְּנֶגֶד הֲרוּגֵי בֵּיתָר. דְּאָמַר רַב מַתְנָא: אוֹתוֹ הַיּוֹם שֶׁנִּיתְּנוּ הֲרוּגֵי בֵּיתָר לִקְבוּרָה תִּקְנוּ בְּיַבְנֶה ״הַטּוֹב וְהַמֵּטִיב״. ״הַטּוֹב״ — שֶׁלֹּא הִסְרִיחוּ, ״וְהַמֵּטִיב״ — שֶׁנִּיתְּנוּ לִקְבוּרָה.
With regard to the origins of the four blessings of Grace after Meals, Rav Naḥman said:
Moses instituted for Israel the first blessing of: Who feeds all, when the manna descended for them and they needed to thank God.
Joshua instituted the blessing of the land when they entered Eretz Yisrael.
David and Solomon instituted the third blessing: Who builds Jerusalem, in the following manner:
David instituted “…on Israel Your people and on Jerusalem Your city…” as he conquered the city,
and Solomon instituted “…on the great and Holy Temple…” as he was the one who built the Temple.
They instituted the blessing: Who is good and does good, at Yavne in reference to the slain Jews of the city of Beitar at the culmination of the bar Kokheva rebellion. They were ultimately brought to burial after a period during which Hadrian refused to permit their burial. As Rav Mattana said: On the same day that the slain of Beitar were brought to burial, they instituted the blessing: Who is good and does good, at Yavne. Who is good, thanking God that the corpses did not decompose while awaiting burial, and does good, thanking God that they were ultimately brought to burial.

Remembering Affliction to Inspire Gratitude
ואמר ואכלת ושבעת וברכת כי תזכור עבודת מצרים וענוי המדבר וכאשר תאכל ותשבע בארץ הטובה תברך עליה את השם ורבותינו (ברכות מח) קבלו שזו מצות עשה וטעמו ותברך את ה' אלקיך וכן ועשית מעקה לגגך (להלן כב ח) וכן ועשית פסח לה' אלקיך (להלן טז א) ולקחת מראשית כל פרי האדמה (להלן כו ב) ורבים כן וטעם על הארץ הטובה כמו ועל הארץ הטובה יצוה שתברכהו בכל עת שתשבע על השובע ועל הארץ שנתן לך שינחילנה לך לעולמים ותשבע מטובה והנה חיוב המצוה הזאת בכל מקום:
And it stated, "And you will eat, and be satiated and bless," since you will remember the work of Egypt and the affliction of the wilderness. And when you will eat and be satiated in the good land, you will bless God about it. And our rabbis (Berakhot 48b) received the tradition that this is a positive commandment - and its explanation is that you shall bless the Lord, your God. And so [too], "and you will make a parapet for your roof" (Deuteronomy 22:8); and so [too] "and you will make a Pesach sacrifice to the Lord, your God" Deuteronomy 16:1); [and so too,] "And you will take from the beginning of all the fruit of the land" (Deuteronomy 26:2); and there are many [other examples] like this. And the explanation of "about the good land" is as [if it were written], "and about the good land." He commanded that you should bless Him at every time about the satiation and the land that He gave you - that he gave it as an eternal inheritance to you, and you will be satiated from its goodness. But behold, the obligation of this commandment is in every place.
The Rabbinic Definition of "Being Satisfied"...
אביי אמר לעולם לא תיפוך התם בקראי פליגי הכא בסברא פליגי התם בקראי פליגי רבי מאיר סבר ואכלת זו אכילה ושבעת זו שתיה ואכילה בכזית ורבי יהודה סבר ואכלת ושבעת אכילה שיש בה שביעה ואיזו זו בכביצה
Abaye said: Actually, do not reverse the opinions. There, they disagree with regard to the interpretation of verses, while here, they disagree with regard to logical reasoning. How so? There, with regard to zimmun, they disagree with regard to the interpretation of verses. Rabbi Meir holds that the verse: “And you shall eat and be satisfied and bless the Lord your God” (Deuteronomy 8:10) should be understood as follows: “And you shall eat,” that is eating; “and be satisfied,” that is drinking. The standard halakhic principle is that eating is defined as the consumption of an olive-bulk. And Rabbi Yehuda holds: “And you shall eat and you shall be satisfied” refers to eating that includes satisfaction. And what is considered eating with satisfaction? It is consumption of an egg-bulk.
...Or Not!
דָּרֵשׁ רַב עַוִּירָא, זִמְנִין אָמַר לַהּ מִשְּׁמֵיהּ דְּרַבִּי אַמֵּי וְזִמְנִין אָמַר לַהּ מִשְּׁמֵיהּ דְּרַבִּי אַסִּי: אָמְרוּ מַלְאֲכֵי הַשָּׁרֵת לִפְנֵי הַקָּדוֹשׁ בָּרוּךְ הוּא: רִבּוֹנוֹ שֶׁל עוֹלָם, כָּתוּב בְּתוֹרָתֶךָ ״אֲשֶׁר לֹא יִשָּׂא פָנִים וְלֹא יִקַּח שֹׁחַד״, וַהֲלֹא אַתָּה נוֹשֵׂא פָּנִים לְיִשְׂרָאֵל, דִּכְתִיב: ״יִשָּׂא ה׳ פָּנָיו אֵלֶיךָ״?! אָמַר לָהֶם: וְכִי לֹא אֶשָּׂא פָּנִים לְיִשְׂרָאֵל, שֶׁכָּתַבְתִּי לָהֶם בַּתּוֹרָה ״וְאָכַלְתָּ וְשָׂבָעְתָּ וּבֵרַכְתָּ אֶת ה׳ אֱלֹהֶיךָ״, וְהֵם מְדַקְדְּקִים [עַל] עַצְמָם עַד כְּזַיִת וְעַד כְּבֵיצָה.
After citing the halakha that one who eats a quantity of food that does not satisfy his hunger is obligated by rabbinic law to recite Grace after Meals, the Gemara cites a related homiletic interpretation. Rav Avira taught, sometimes he said it in the name of Rabbi Ami, and sometimes he said it in the name of Rabbi Asi: The ministering angels said before the Holy One, Blessed be He: Master of the Universe, in Your Torah it is written: “The great, mighty and awesome God who favors no one and takes no bribe” (Deuteronomy 10:17), yet You, nevertheless, show favor to Israel, as it is written: “The Lord shall show favor to you and give you peace” (Numbers 6:26). He replied to them: And how can I not show favor to Israel, as I wrote for them in the Torah: “And you shall eat and be satisfied, and bless the Lord your God” (Deuteronomy 8:10), meaning that there is no obligation to bless the Lord until one is satiated; yet they are exacting with themselves to recite Grace after Meals even if they have eaten as much as an olive-bulk or an egg-bulk. Since they go beyond the requirements of the law, they are worthy of favor.

Tear down their altars, smash their pillars, put their sacred posts to the fire, and cut down the images of their gods, obliterating their name from that site.
