The Gemara introduces a statement by the word Gufa, which refers to a previously learned teaching. This teaching states that those standing behind the Kohanim are not included in the blessing, as one must be in front of the Kohanim to receive it. Rav Sheshet clarifies that this does not mean a tall person blocking a short person, as long as both are in front. Similarly, furniture or other objects within the synagogue do not constitute a barrier between the recipient of the blessing and the Kohanim. The discussion then extends to physical barriers, citing a teaching that "even an iron curtain, an iron wall, cannot separate between Bnei Yisrael and their Father in Heaven."
The Tosafot clarifies this teaching, explaining that the wall in question refers to a situation where it was erected without extenuating circumstances. If, however, there was a compelling need to put up the wall, it is not considered worse than farmers in a field who cannot reach the synagogue but still receive the priestly blessing. Thus, if a wall was necessary due to extenuating circumstances within the synagogue, it does not create a separation. This concept, "even an iron wall cannot separate Bnei Yisrael," has also been interpreted as a moral lesson: nothing should separate Jews from each other, encouraging camaraderie and peace.
A famous question arises in the Ketubot regarding individuals standing to the sides of the Kohanim, not directly in front. Rav Sheshet, quoting Abba Mor Bar Rav Ashi, brings a Mishna from the laws of Parah Adumah to address this. The Mishna discusses a Kohen or an individual performing the sprinkling of the Parah Adumah waters. If he intended to sprinkle a vessel in front of him but accidentally sprinkled a vessel behind him, the sprinkling is invalid. This is because one must have specific intention for the item being purified. However, if he intended to sprinkle in front but the waters went to the sides, the sprinkling is valid. This implies that "side" is considered "front" for the purpose of intention. Therefore, just as for Parah Adumah, the sides are considered "front," so too for the Kohanim, those standing to their sides are considered "front" and receive the blessing.
Further clarification is needed regarding "front" and "sides." It is understood that if people on the sides are behind the Kohanim, even diagonally, it is acceptable. Maran Beit Yosef holds that even if they are parallel to the Kohanim, meaning a straight line can be drawn from the Kohen's face to the person's face, it is still considered acceptable. In such a case, Maran stipulates that the person should turn their body towards the Kohen, whereas normally everyone faces the Hechal. The question then arises in Halakha about people in synagogues who are on the sides, especially when there are many Kohanim whose line extends beyond them, placing some congregants in the middle of the line of Kohanim. Do these individuals need to move behind the entire line of Kohanim? The Halakha states they do not need to move. The underlying logic is that the concern is for someone who is not interested in the blessing and thus does not bother to position themselves correctly. If someone has Kohanim in front of them, they are not considered lazy or delinquent, even if the line of Kohanim extends beyond their position.
When the Sefer Torah is opened for reading, no talking is permitted. The term "amdu" in this context means "they were silent," not "they stood." The verse states that the ears of the entire nation must pay attention to the Sefer Torah. The Tosafot poses a question from Gemara Berachot, where Rav Sheshet is described as turning his face away from the Sefer Torah and learning during the reading, saying, "They are doing their thing, and I am doing my thing." One answer provided is that Rav Sheshet turned his face, implying that the prohibition on talking applies when one is facing the Sefer Torah. If one turns away, learning might be permitted. However, the Gemara states that Rav Sheshet was blind, and therefore exempt from hearing the reading. Another answer is that Rav Sheshet was a unique individual, a "man of Torah," who did not waste a minute of his time. As long as others in the synagogue were seeing the Sefer Torah, he was permitted to learn. However, since we do not have such a level of "man of Torah" today, the Halakha is that when the Sefer Torah is opened, one must pay full attention to the reading, not read, learn, or study Halakha.
The Rambam holds that if a Kohen washed his hands for Netilat Yadayim in the morning and kept them clean, he can rely on that washing for the priestly blessing. However, Maran does not accept this opinion and requires the Kohen to wash his hands again. We only rely on the Rambam's opinion in extenuating circumstances, such as a lack of water or if the Kohen is the Hazan and the only Kohen present. In such a case, he cannot leave the prayer to wash his hands, but he can still perform the priestly blessing if he can return to the prayer. Otherwise, the Kohen must wash his hands. The custom is for a Levi to wash the hands of the Kohanim; if no Levi is present, a firstborn son performs this custom.
The Gemara recounts that students asked Rabbi Elazar ben Shamua what he attributed his long life to. He replied, "I never made the synagogue a shortcut." This means he never used the synagogue as a mere passageway to avoid going around a block of houses. This is forbidden out of respect for the synagogue. The explanation is that even in cases where it might be permissible, such as entering to learn and then using it as a shortcut upon leaving, Rabbi Elazar ben Shamua was stringent. The second thing he mentioned was, "I did not step on the heads of the holy nation." In ancient times, students sat on the floor. If a rabbi entered a lecture after everyone was seated, walking between them would appear as if he were stepping over their heads, which is disrespectful. Again, even in cases where it might have been permissible, such as if students were sitting on benches, or if he was the lecturer needing to reach the front, he was stringent not to give the impression of disrespect. The third thing he said was, "I never performed the priestly blessing without a blessing." One interpretation is that the blessing recited by the Kohanim before the priestly blessing, "who has sanctified us with the sanctity of Aaron and commanded us to bless His people Israel with love," was not originally mandatory, as one does not make a blessing on a blessing (e.g., before Birkat Hamazon). Rabbi Elazar ben Shamua was stringent to recite it anyway. Another interpretation relates to the phrase "to bless His people Israel with love." This means the Kohen must love the people and harbor no animosity. Rabbi Elazar ben Shamua always had this love, enabling him to always perform the blessing. A third interpretation suggests he was referring not to the mandatory blessing, but to the voluntary prayers of Yehi Ratzon that the Kohen says before ascending and after descending the Dukhan. He was careful to recite these as well.
The blessing the Kohanim recite is: "Blessed are You, Lord our God, King of the universe, who has sanctified us with the sanctity of Aaron and commanded us to bless His people Israel with love." The numerical value of the Hebrew word for "love" (Ahava) is 13. When two Jews express love for each other, it totals 26, which is the numerical value of God's name, signifying the presence of the Shechinah. This is alluded to in the verse, "When a person has love... I am the Lord."
When the Kohen moves his legs to ascend the Dukhan (the platform), which is typically during the Ritzah part of the prayer, he recites a Yehi Ratzon: "May this blessing that You have commanded us to bless the Jewish people not be a stumbling block, and may we succeed in making the blessing in the proper way." This is a prayer that their sins do not interfere with the blessing. The question arises as to the timing of this Yehi Ratzon. If said on the way up, they might miss answering Modim Derabbanan. Therefore, the Halakha states they should answer Modim Derabbanan first, and then, once they are fully on the Dukhan, they recite this Yehi Ratzon. At this point, they are still facing the Hechal.
After the priestly blessing, when the Kohanim turn their faces away from the congregation, they recite a special prayer. It is noteworthy that during the priestly blessing, the Kohanim face the congregation, even if it means turning their backs to the Hechal, which is usually avoided and requires special permission. This highlights the importance of the priestly blessing. Once the blessing is complete, they turn back to face the Hechal and recite a prayer. Rav Hisda, escorting Rav Ukva, heard him say, "Master of the Universe, we have done what You commanded us. Now, please, God, fulfill what You promised us: 'Look from the heavens where You are and bless the nation.'" This refers to God's promise, as learned in the Midrash Tanchuma, that when the Kohanim place His name upon the people, He will bless them. The blessing is twofold: the Kohanim bless, and the Shechinah also bestows a blessing. Thus, after their part, the Kohanim ask God to fulfill His promise. The Kohanim are not permitted to lower or bend their hands until they turn around after the blessing is over; as long as they face the congregation, their hands must remain raised.
The Gemara emphasizes precise timing for everyone involved in the priestly blessing: the Hazan (who prompts the Kohanim), the Kohanim (who respond), and the congregation (who answer Amen). Everyone must wait for the preceding person to finish their word, response, or Amen before proceeding. The Hazan should not prompt the Kohanim until they finish their word. The Kohanim must wait for the Hazan to finish before responding, not rushing due to fatigue. The congregation should not answer Amen until the Kohanim have finished their blessing. Finally, the Kohanim should not begin the post-blessing prayer until the congregation has answered Amen to "peace," the last word of the blessing. These prayers said by the Kohanim before ascending and after descending the Dukhan are timed to coincide with other parts of the service. The ascending prayer should conclude with the congregation's Amen to "Who is good is Your name and to You it is fitting to give thanks," and the post-blessing prayer should conclude simultaneously with the congregation's Amen to "Who makes peace." The Kohanim are allowed to turn around only after the Hazan begins "Who makes peace" and must remain at the Dukhan until the Hazan finishes that blessing, only then returning to their seats.
Similar timing applies to the reading of the Sefer Torah. The congregation should not answer Amen until the person making the blessing finishes it. The reader should not begin reading until the person making the blessing and the congregation have finished their Amen. The custom is for the reader to also say Amen aloud to signal completion. If a translator (Meturgeman) is present, he waits for the reader to finish a verse before translating, and the reader waits for the translator to finish before continuing. The person receiving the Maftir aliyah reads the Haftarah. However, out of respect for the Sefer Torah, one cannot simply read the Haftarah. The Halakha requires reading a few passages from the Sefer Torah first. This is why the Maftir section involves repeating a few verses from the end of the Torah portion, not to fulfill the obligation of reading, but as a sign of respect, beginning with the written Torah before moving to the Haftarah.
In ancient times, the Sefer Torah was rolled up with special sheets. The Gemara states that one must wait until the Sefer Torah is completely rolled up before beginning the blessings for the Haftarah. This is a matter of proper conduct (Derech Eretz), so that those rolling the Sefer Torah are not preoccupied and can hear the Haftarah. Rashi explains this: "Until the Sefer Torah is rolled with its sheets, so that the rollers are not distracted from hearing the Haftarah from the mouth of the Maftir."
The Gemara then discusses an old custom: in some places, the Aron Kodesh was not in the prayer room. Before bringing the Sefer Torah into the room, the Teva (reader's platform) would be draped with mats and rugs. After the reading, the Halakha states that the Teva should not be undraped or cleaned in front of the congregation, as this would be disrespectful to the congregation (Kavod Tzibbur). Instead, the Sefer Torah should be returned to its place, and the attendant (Shammash) should clean the Teva afterwards, when the congregation is not waiting. The Gemara emphasizes the importance of Kavod Tzibbur, stating that the attendant should not undrape the Teva until the congregation has left. There is a dispute between the Sages: one opinion holds that the congregation should not leave until the Sefer Torah is returned to its original place. Shmuel says, "until it leaves," meaning until it exits the prayer room, not necessarily its final resting place. The Gemara resolves this by stating it depends on the number of doors in the synagogue. If there are two doors, once the Sefer Torah is lifted to be taken out of door A, the congregation can leave through door B, as it would be disrespectful for them to leave through the same door before the Sefer Torah. If there is only one door, the Sefer Torah must exit first, and the people follow. Today, with an Aron Kodesh, the Halakha advises remaining in the synagogue at least until the Sefer Torah is returned to the Aron.
Rava, quoting Bar Ahina, explains the logic for following the Sefer Torah from the verse, "You shall follow the Lord your God." Just as one follows God, so too should one follow the Sefer Torah, with the people walking behind it. During the priestly blessing, the people would recite specific verses to demonstrate their acceptance of the blessing, showing that the blessings are "pleasant." They would recite verses referring to God's blessings. The first verse: "Bless the Lord, His angels, mighty in strength, who perform His word, hearkening to the voice of His word." The second: "Bless the Lord, all His hosts, His ministers, who perform His will." The third: "Bless the Lord, all His works, in all places of His dominion; bless the Lord, O my soul." These three verses correspond to the three verses of the priestly blessing. The Gemara discusses when these verses are recited, specifically after each mention of God's name in the priestly blessing. Some say one verse is recited after each of the three blessings; others say all three verses are recited after each blessing.
On a day when Musaf is recited, such as a holiday, new verses are needed for the priestly blessing because the previous ones were already recited during the Shacharit prayer. The three new verses for Musaf are: "Behold, bless the Lord, all you servants of the Lord, who stand in the house of the Lord in the nights. Raise your hands in holiness and bless the Lord. May the Lord bless you from Zion, He who dwells in Jerusalem." The Gemara questions why the third verse, "May the Lord bless you from Zion, He who dwells in Jerusalem," is chosen, as it is from a different chapter of Psalms (135) than the first two (134). The Gemara explains that the chosen verse refers to God blessing the Jewish people. The Gemara wanted to use a verse that refers to the Jewish people blessing God, to maintain consistency with the other two verses that speak of praising God. Therefore, even though "Blessed be the Lord from Zion" is in the same chapter as the first two, it is not used because it speaks of being blessed, not blessing God.
On a fast day, the priestly blessing is recited during the Mincha prayer. Normally, it is not recited during Mincha on a regular day due to concern that people might have eaten and be inebriated, which would disqualify a Kohen from giving the blessing. However, on a fast day, no one is eating, so it is permissible. Since these verses were already said in Shacharit, new ones are needed for Mincha. The Mincha prayer on a fast day is a critical time for introspection and repentance, a time when the gates of heaven are open. Therefore, the three verses chosen for Mincha on a fast day are different; they are prayers for forgiveness, not blessings. The first verse: "For Your sake, Lord, forgive our iniquity, for it is great." The next: "Hope of Israel, its redeemer in time of trouble, why are You like a stranger in the land, like a traveler who turns aside to lodge for a night?" The third: "Why should You be like a man confounded, like a mighty man who cannot save? Yet You, Lord, are in our midst, and we are called by Your name; do not abandon us." These verses speak of seeking God's forgiveness and presence. The Gemara then lists three additional verses that can be recited: "May He bless you, and may He guard you. May He cause His countenance to shine upon you, and may He be gracious to you. May He lift up His countenance to you, and may He grant you peace."
The Gemara then discusses the timing of these verses. Rav Yosef says they are recited between each of the three blessings of the Kohanim. Others say they are recited whenever God's name is mentioned. Some hold that one verse is recited for each blessing, while others say all three verses are recited at each interval. The Gemara then quotes a verse from Psalms: "Fortunate is every person who fears the Lord, who walks in His ways." The benefits of fearing God are listed: "You shall eat the labor of your hands; you shall be happy, and it shall be well with you. Your wife shall be like a fruitful vine in the innermost parts of your house; your children like olive shoots around your table." This means a good livelihood, happiness in this world and the next, a fruitful wife, and righteous children. The verse concludes: "Behold, thus shall the man who fears the Lord be blessed." This is often interpreted as a summary of the preceding benefits. However, Hacham Ovadia explained it differently: when one sees all these blessings that come from fearing God, then when a person blesses a friend, the best blessing to give is "May you have fear of Heaven." This single blessing encompasses all other good things, such as livelihood, a good wife, and children, as Moshe Rabbeinu taught: "What does the Lord your God ask of you? Only to fear the Lord your God." Once one has fear of Heaven, all other blessings fall into place.
