Talmud - Berakhot 12a ברכות י״ב א׳

However, if you say that they would omit: Who creates light, and would recite: An abounding love, on what basis would you conclude that failure to recite one of the blessings recited before Shema does not prevent one from reciting the other? In that case, one could offer another reason why only a single blessing is recited. Perhaps the fact that they did not recite: Who creates light was because the time for the recitation of: Who creates light, had not yet arrived, as the sun had yet to rise. The blessings of the priestly watch are recited in the early morning hours, long before sunrise. However, afterward, when the time to recite: Who creates light arrived, they would recite it. From the conclusion drawn by Rabbi Shimon ben Lakish, that failure to recite one of the blessings recited before Shema does not prevent one from reciting the other, it is clear that the blessing recited by the members of the priestly watch was: Who creates light.

As this deductive reasoning seems coherent and convincing, the Gemara asks: And if this halakha is based on inference, and not on an explicit statement, what of it? There seems to be no other way to interpret Rabbi Shimon ben Lakish’s statement.

The Gemara answers: If this conclusion were based on an inference, one could say that actually they recited: An abounding love, and when the time to recite: Who creates light arrived, they would recite it. In that case, what is the meaning of: Failure to recite one of the blessings recited before Shema does not prevent one from reciting the other? Rabbi Shimon ben Lakish meant that failure to recite the correct order of the blessings does not prevent one from fulfilling his obligation. Even if one recites: An abounding love before: Who creates light, he fulfills his obligation. Rabbi Shimon ben Lakish did not refer to a case where only one of the blessings was recited. Consequently, one cannot infer from his statement his opinion regarding the identity of the single blessing.

The Gemara related above that the priests in the Temple read the Ten Commandments, along with the sections of Shema, VeHaya im Shamoa, VaYomer, True and Firm, Avoda, and the priestly benediction.

Rav Yehuda said that Shmuel said: Even in the outlying areas, outside the Temple, they sought to recite the Ten Commandments in this manner every day, as they are the basis of the Torah (Rambam), but they had already abolished recitation of the Ten Commandments due to the grievance of the heretics, who argued that the entire Torah, with the exception of the Ten Commandments, did not emanate from God (Jerusalem Talmud). If the Ten Commandments were recited daily, that would lend credence to their claim, so their recitation was expunged from the daily prayers.

That was also taught in a baraita that Rabbi Natan says: In the outlying areas, they sought to recite the Ten Commandments in this manner, but they had already abolished their recitation due to the grievance of the heretics.

The Gemara relates that several Sages sought to reinstitute recitation of the Ten Commandments, as Rabba bar bar Ḥana thought to institute this in the city of Sura, but Rav Ḥisda said to him: They already abolished them due to the grievance of the heretics.

So too, Ameimar thought to institute this in the city of Neharde’a. Rav Ashi, the most prominent of the Sages in that generation, said to him: They already abolished them due to the grievance of the heretics.

We learned in a mishna in tractate Tamid that on Shabbat a single blessing is added to bless the outgoing priestly watch. The Gemara asks: What is that single blessing? Rabbi Ḥelbo said: As they finished their service, the outgoing priestly watch would say to the incoming priestly watch: May He who caused His Name to dwell in this house cause love and brotherhood, peace and camaraderie to dwell among you.

We learned in the mishna: Where the Sages said to recite a long blessing, one may not shorten it, and vice-versa. The Gemara proceeds to address a particular problem arising from conclusions drawn from this mishna. Before addressing the primary problem, however, a simpler, secondary issue is raised: Obviously, in a case where one took a cup of wine in his hand and thought it was beer, and began reciting the blessing thinking it was beer, i.e., he intended to recite the appropriate blessing on beer: By Whose word all things came to be, and upon realizing that it was wine, he concluded the blessing with that which is recited over wine: Who creates the fruit of the vine, he fulfilled his obligation. In that case, even had he recited: By Whose word all things came to be, as he originally intended, he would have fulfilled his obligation, as we learned in a mishna: If one recited the general blessing: By Whose word all things came to be, over all food items, he fulfilled his obligation after the fact, even if ab initio another blessing was instituted to recite before eating that food. Therefore, if he reconsidered and concluded the blessing with the ending of the blessing over wine, he fulfilled his obligation.

However in a case where one took a cup of beer in his hand and thought it was wine, and began reciting the blessing thinking it was wine, meaning he intended to recite: Who creates the fruit of the vine, and upon realizing that it was beer he concluded the blessing with that which is recited over beer: By Whose word all things came to be, what is the halakha?

Ostensibly, this blessing is comprised of two sections. The first section, during which he intended to recite: Who creates the fruit of the vine, cannot fulfill his obligation as it is an inappropriate blessing to recite over beer. However, in the second section he recited: By Whose word all things came to be, the appropriate blessing. The dilemma, then, is: Do we follow the essence of the blessing, the first section, or do we follow the conclusion of the blessing?

Come and hear a proof from what was taught in a baraita with regard to a similar case: If, in the morning prayer, one began the blessings prior to the recitation of Shema appropriately with: Who creates light, and concluded with the formula of the evening prayer: Who brings on evenings, he did not fulfill his obligation. However, if one did the opposite, and commenced with: Who brings on evenings, and concluded with: Who creates light, he fulfilled his obligation.

Similarly, if, in the evening prayer, one commenced the recitation of Shema with: Who brings on evenings and concluded with: Who creates light, he did not fulfill his obligation. If one commenced with: Who creates light and concluded with: Who brings on evenings, he fulfilled his obligation.

The baraita summarizes that the general principle is: Everything follows the conclusion of the blessing. Based on this principle, the question with regard to a blessing recited over food and drink posed above can be resolved.

This proof is rejected: There, in the case of the blessing recited over the radiant lights, it is different, as one recites: Blessed…Who forms the radiant lights, and similarly, in the evening one recites: Blessed…Who brings on evenings. Since these are long blessings that conclude with a second blessing summarizing their content, one could assert that everything follows the conclusion. However, in the case of short blessings, such as: By Whose word all things came to be, or: Who creates the fruit of the vine, ostensibly, if there is a problem with the first part of the blessing, the entire blessing is nullified.

The distinction between the blessing recited over the radiant lights and the blessings recited over food and drink stems from the assumption that the conclusion: Blessed…Who fashions the radiant lights, is a complete, independent blessing. However, this is not necessarily so. This works out well according to Rav, who said: Any blessing that does not include mention of God’s name is not considered a blessing, and since: Who creates light, includes God’s name, it constitutes a complete, independent blessing. That works out well. However, according to Rabbi Yoḥanan, who said: Any blessing that does not include mention of God’s sovereignty, i.e., our God, King of the universe, is not considered a blessing, what can be said to distinguish between the conclusion of the blessings over food and drink and the blessing over the radiant lights? Since the conclusion: Who creates light, does not mention God’s sovereignty, it does not constitute a complete, independent blessing.

The Gemara responds: Rather, Rabbi Yoḥanan also holds that the blessing over the radiant lights is a complete blessing. Since Rabba bar Ulla said: Who creates darkness, is mentioned during the day and: Rolling away the light before the darkness, is mentioned at night in order to mention the attribute of day at night and the attribute of night in the day, the beginning of the blessing in which God’s sovereignty is mentioned day and night is appropriate to both day and night, and when one recites the blessing with God’s name and mentions God’s sovereignty at the beginning of the blessing, it refers to both day and night. Therefore, no proof can be cited from the blessing over the radiant lights to the blessings recited over food and drink.

The Gemara attempts to cite an additional proof: Come and hear another solution based on what we learned in the latter clause of the baraita cited above: The general principle is: Everything follows the conclusion of the blessing. What does the phrase: The general principle is, come to include beyond the detailed example cited in the baraita? Does it not come to include the case that we stated, that both in the case of a long blessing and the case of a short blessing, the conclusion of the blessing is the determining factor?

The Gemara rejects this: No, the principle is cited to include a case of bread and dates. The Gemara clarifies: What are the circumstances of the dilemma with regard to the blessings on these food items? If you say that it is a case where one ate bread and thought that he ate dates, and commenced reciting the blessing thinking it was dates; then, upon realizing that it was bread, he concluded the blessing with that which is recited over bread, isn’t that our dilemma, as this case is identical to the one involving wine and beer?

The Gemara answers: No; this general principle is only necessary to teach a special case, where one ate dates and thought that he ate bread, and commenced reciting the blessing thinking they were bread. Upon realizing that they were dates, he concluded the blessing with that which is recited over dates. In that case he fulfilled his obligation, as even had he concluded the blessing with that which is recited over bread, he would have fulfilled his obligation.

What is the reason that had he concluded with the blessing recited over bread he would have fulfilled his obligation to recite a blessing over dates? This is because dates also provide a person sustenance. While ab initio one should not recite the blessing for bread over dates, after the fact, if one did so, he fulfilled his obligation. It is with regard to this particular situation that the baraita established the principle: Everything follows the conclusion of the blessing. Ultimately, the dilemma regarding a blessing with an inappropriate opening and an appropriate conclusion remains unresolved.
The Gemara proceeds to discuss the formula for the blessings recited along with Shema.

Rabba bar Ḥinnana Sava said in the name of Rav: One who did not recite: True and Firm [emet veyatziv] at the beginning of the blessing of redemption that follows Shema in the morning prayer, and: True and Trustworthy [emet ve’emuna] in the evening prayer, he did not fulfill his obligation. An allusion to the difference in formulation between morning and evening is, as it is stated: “To declare Your kindness in the morning and Your faith in the nights” (Psalms 92:3). In the morning, one must mention God’s loving-kindness, while in the evening one is required to emphasize the aspect of faith.

And Rabba bar Ḥinnana Sava said in the name of Rav: One who is praying, when he bows in the appropriate places, he bows when he says: Blessed, and when he subsequently stands upright, he stands upright when he says God’s name.

Shmuel, who was Rav’s colleague and significantly outlived him, said: What is Rav’s reason for saying that one should stand upright at the mention of God’s name? As it is written: “The Lord, who raises the bowed” (Psalms 146:8); one stands upright at the mention of God’s name to recall that it is God who raises the bowed.

The Gemara raises an objection based on what we learned in praise of a priest: “And he was afraid before My name” (Malachi 2:5), indicating that one must be humbled and not upright before God’s name.

The Gemara responds: Is it written: At My name? Before My name, is written, meaning that one is humbled and bows prior to the mention of God’s name, when he says: Blessed.

The Gemara relates: Shmuel said to Ḥiyya bar Rav: Son of Torah, come and I will tell you a great saying that your father said. Your father said the following: When one bows, he bows when he says: Blessed, and when he stands upright, he stands upright when he says God’s name.
