Talmud - Berakhot 46b ברכות מ״ו ב׳

and there are among these blessings that one who recites it concludes reciting it with: Blessed, but does not begin reciting it with: Blessed. The blessing: Who is good and does good, one who recites it begins to recite it with: Blessed, but does not conclude reciting it with: Blessed. This proves by inference that it is an independent blessing.

And Rav Naḥman bar Yitzḥak said: Know that the blessing: Who is good and does good, is not required by Torah law, as it is eliminated in the house of the mourner, as it was taught in a baraita according to the opinion of Rabbi Akiva: What do they say in the house of the mourner? Blessed…Who is good and does good. Rabbi Akiva says: Blessed…the true Judge.

The first opinion in the baraita is challenged: Who is good and does good, yes, it is recited in the house of the mourner, the true Judge, no, it is not recited? Rather, say: Who is good and does good, is recited as well.

The Gemara recounts: Mar Zutra happened to come to Rav Ashi’s home when an incident of mourning befell Rav Ashi. Mar Zutra began a combined blessing and recited:
Who is good and does good,
God of truth, the true Judge,
Who judges with righteousness, takes away with justice,
and is the ruler of His world to do in it as He wills,
as all His ways are just,
that all is His and we are His people and His servants,
and in everything we are obligated to thank Him and bless Him,
Who repairs the breaches in Israel,
He will repair this breach in Israel for life.
Mar Zutra included both: Who is good and does good, as well as mourning and acceptance of divine justice.

Returning to the original topic, it was mentioned above that one interrupts his meal to form a zimmun with two others who finished eating. The question is raised: To where does he return when he finishes his own meal and must begin to recite his own Grace after Meals? Rav Zevid in the name of Abaye said: He returns to the beginning and recites the entire Grace after Meals. And the Rabbis say: He returns to the place that he stopped. And the halakha is: He returns to the place that he stopped, i.e., to the beginning of the second blessing.

On the topic of meals, the Gemara relates the following: The Exilarch said to Rav Sheshet: Although you are elderly Sages, the Persians are more expert than you with regard to the required etiquette at meals. The Persian custom is that when there are two divans on which they would recline, the greater of the two people reclines first and the person second to him in importance reclines on the divan above him, alongside his head. When there are three divans, the greatest of the three reclines on the middle divan, the one second to him in importance reclines on the divan above him, and the one third to him in importance reclines on the divan below the greatest of the three.

Rav Sheshet said to the Exilarch that the custom is flawed. If the greater wishes to speak with the one second to him in importance who is reclining above his head, he must straighten up and sit and only then will he be able to speak to him. The Exilarch answered: The Persians are different, as they signal and communicate with hand gestures, especially during mealtimes, so there is no need to sit up.

Rav Sheshet asked the Exilarch about the Persian practice with regard to the first waters. When washing hands before the meal, from where do they begin? The Exilarch said to him: They begin from the greatest.

Rav Sheshet asked: If that is so, should the greatest person present sit and keep his hands clean and wait until everyone has washed so that they may all be served? The Exilarch said to him: They bring him his table [takka] immediately, as the custom was that each person ate at his own private table, and they brought the table before the greatest person present immediately after he washed so that he need not wait for the others.

Rav Sheshet asked the Exilarch about the Persian practice with regard to the final waters. When washing hands after the meal, from where do they begin? The Exilarch said to him: They begin with the least significant of the attendees.

Rav Sheshet said: If so, should the greatest person present sit with dirty hands until everyone washes his hands? The Exilarch said to him: They do not remove the table from before him until the water reaches him; he can continue eating while the others are washing.

Rav Sheshet said: In terms of conduct at a meal, I know a baraita, as it was taught: What is the order of reclining? When there are two divans on which they would recline, the greater of the two people reclines first, and the person second to him in importance reclines on the divan below him. When there are three divans, the greatest of the three reclines first, on the middle divan, the one second to him in importance reclines on the divan above him, and the one third to him in importance reclines on the divan below the greatest of the three. The first waters before the meal, they begin with the greatest person present. The final waters; when they are five people, they begin with the greatest person present. When they are more than that, even one hundred, they begin the final waters with the least significant of the attendees until they reach the five greatest present, at which point they return and begin with the greatest present. And to the place that the final waters return the blessing also reverts, and the greatest present, the first among the final five to wash his hands, recites Grace after Meals.

This baraita supports the opinion of Rav, as Rabbi Ḥiyya bar Ashi said that Rav said: Whoever washes his hands first at the end of the meal is designated to recite the blessing of Grace after Meals.

Similarly, the Gemara relates: Rav and Rabbi Ḥiyya were seated at a meal before Rabbi Yehuda HaNasi. Rabbi Yehuda HaNasi said to Rav: Stand, wash your hands. Rabbi Ḥiyya saw that Rav was trembling in fear that perhaps he had conducted himself improperly during the meal and therefore had to wash his hands. Rabbi Ḥiyya said to him: Son of noblemen, he is saying to you to review Grace after Meals, as the first to wash his hands after the meal is honored with leading the blessing.

The Gemara continues to discuss the topic of washing after a meal. The Sages taught: Although it is customary to defer to greater people, nevertheless, one shows deference neither on roads nor on bridges,
