Text Snapshot

The Rambam enumerates the birkat hamazon:

"הַזָּן אֶת הָעוֹלָם... נוֹדֶה לְךָ... רַחֵם... הָאֵל אָבִינוּ מַלְכֵּנוּ... הַטּוֹב וְהַמֵּטִיב. בְּרָכָה רְבִיעִית שֶׁתִּקְּנוּ חַכְמֵי הַמִּשְׁנָה."^1 While the first three blessings are presented without explicit attribution here, the fourth, "הטוב והמטיב," is distinctly characterized as a takanah of the Chachmei haMishnah.

Readings

Rambam, Hilchot Brachot 2:1-2

The Rambam's more detailed account clarifies that the first bracha was instituted by Moshe, the second by Yehoshua, and the third by David and Shlomo, or Anshei Knesset HaGedolah (depending on the version).^2 This provides the context for the takanah of Chachmei haMishnah for the fourth bracha.

Rashi, Brachot 48b s.v. "אמר רב נחמן"

Rashi explicitly links the fourth bracha to the harugei Beitar, emphasizing its institutionalization after a specific historical tragedy, reinforcing its later, rabbinic origin.^3

Friction

The "Missing" Takanah

Kushya: Why does the Rambam in Hilchot Tefillah 5:2:5 explicitly attribute "הטוב והמטיב" to Chachmei haMishnah, yet omits the specific takanah of the first three blessings here, despite detailing them in Hilchot Brachot? Terutz: The Rambam's focus in Hilchot Tefillah 5 is on the order and content of the tefillot. The explicit mention of "תִּקְּנוּ חַכְמֵי הַמִּשְׁנָה" for the fourth bracha serves to highlight its distinct status as a later, additional takanah (post-harugei Beitar), rather than part of the original, progressive set established by earlier figures. The comprehensive historical-halachic tracing is reserved for Hilchot Brachot, where the source of chiyuv is paramount.^4

Intertext

The Gemara in Brachot 48b-49a is the foundational source for the specific takanot and their historical context.^5 The Birkat HaTov VeHaMeitiv is connected to the miracle where the bodies of those slain at Beitar did not decompose, allowing for proper burial.^6

Psak/Practice

The distinction between the first three blessings (generally considered d'Oraita or earlier takanot) and the fourth (d'Rabbanan) impacts halachic stringency. While all are obligatory, the wording of the first three is more rigid, whereas the fourth, given its later origin, might allow for slightly more leniency bedi'eved regarding precise nusach, though standard practice maintains the prescribed text.^7

Takeaway

The layered takanot of Birkot HaMazon reflect a dynamic halachic tradition, evolving to incorporate new expressions of gratitude and national memory within a core framework.
