The Mishna rules that if one vows to bring a mincha (meal offering) but cannot recall which type, they must bring all five standard types. Abaye explains that this ruling can also align with Rabbi Shimon's position, which recognizes a sixth type consisting of both wafers and loaves; he argues that bringing the wafers and loaves separately covers the possibility of the combined type as well. The Gemara raises several practical difficulties regarding this possibility but resolves them all.

Rav Kahana asks Rav Ashi why the person in the above case would not also need to offer a minchat nesachim (a meal offering brought with libations), given Rava's view that it can be brought as a voluntary offering. Rav Ashi identifies five distinct differences between a minchat nesachim and other voluntary meal offerings, demonstrating that someone in doubt about their vow would certainly not have been referring to an offering so fundamentally different.

The Rabbis and Rebbi disagree in the Mishna regarding a case where one says, "I vowed to bring a mincha of esronim in one vessel, but I do not remember how many." The dispute centers on whether they must bring sixty esronim in one bowl or every amount from one to sixty in sixty separate bowls. The Gemara suggests five different explanations for the nature of this debate and analyzes each suggestion.

The Mishna explains the minimum value one must provide when vowing to bring wood, frankincense, gold, silver, or copper to the Temple. The required amount depends on the phrasing used: if one said, "I vow to bring [the item]," they are required to bring the minimum. However, if one said, "I vowed an amount, but I do not remember what amount," they are required to bring the maximum.

There is a contradiction raised against Rav Bibi, who testified about a case where the blood of a carcass was measured to see if there was enough to convey impurity. This contradicts a Mishna in Eduyot, where others testified that the blood of a dead animal is pure. The Gemara resolves this by explaining that there is a tannaitic debate on the matter and clarifies why those who declare it impure set the requisite amount at a quarter-log (revi'it).

One may offer voluntary wine libations in the Temple, but only in the volumes used for obligatory offerings: three, four, or six log (or a combination thereof). A question is raised: must the pledged libations be offered all at once, or can they be split? This question is asked egarding someone who pledged five log (an invalid single amount): can one "divide" the five - meaning offer four and redeems the fifth or gives it away - or must one wait until one acquires another log to complete a set of six? Although Abaye and Rava both attempted to bring proofs to resolve this, their answers were rejected as inconclusive.

Rabbi Akiva and Rabbi Tarfon disagree over whether one can offer voluntary oil libations. Their debate centers on whether the laws of oil can be derived from the laws of wine.

Regarding ownership, a mincha cannot be brought if it is jointly owned by partners. The Gemara explores why this differs from animal and bird sacrifices, which can be brought by partners.

There are five (or six, according to Rabbi Shimon) types of voluntary mincha offerings: solet (no pre-baking/frying), machavat (pan), marcheshet (deep pan), rekikim (wafers), and challot (loaves). The Mishna delves into various ambiguous formulations used in vows and explains what specific type and quantity the individual is obligated to bring to ensure they fulfill their commitment.

There is a dispute regarding a case where someone vowed to bring a mincha of barley. The Tana Kama says that because such a thing does not exist, we obligate them to bring a mincha of wheat. Rabbi Shimon disagrees and says that what was said is nothing, as there is no voluntary mincha of barley. Chizkiya and Rabbi Yochanan attempt to understand the Tana Kama's position. For Chizkiya, it is based on the view of Beit Shammai who hold that we seize the first expression - the statement "I take upon myself a mincha" already creates an obligation to bring a wheat offering, and what one said afterward (where perhaps it was a retraction) is not accepted at all because it is too late. According to Rabbi Yochanan, who establishes an ukimta for the Mishna, it refers to a case where, when told there is no mincha of barley, the person says that they did not know, and had they known, they would have vowed wheat.

There is another dispute in our Mishna between Chizkiya and Rabbi Yochanan that appears to present opinions opposite to what they said previously, but the Gemara explains the matter. Chizkiya retracted and agreed with Rabbi Yochanan, while Rabbi Yochanan challenged his retraction and explained how Chizkiya could have explained the words of the Mishna according to his original logic.

Zeiri limits the words of the Mishna to a case where one said "I take upon myself a mincha...", but if one did not say "mincha" but rather "I take upon myself barley" or "I take upon myself a barley mincha," we do not apply the principle of seizing the first expression. Rava challenges Rav Nachman regarding Zeiri's words based on our Mishna, but Rav Nachman resolves his challenges.

One who volunteers to bring more than sixty issaron must bring sixty in one vessel and the remainder in another vessel. Why is sixty established as the maximum amount for a single vessel? The Tana Kama explains this based on the day that has the most libations in the Temple - the first day of Sukkot that falls on Shabbat, when they bring libations in the amount of sixty-one issaron. Rabbi Shimon disagrees and says it is based on what can be mixed in one vessel; more than sixty is impossible. The Sages challenge him as to why specifically this number was chosen. Rabbi Shimon responds that this is the case with all measurements established by the Sages. The Gemara challenges Rabbi Shimon, noting that a mincha is valid even if it was not actually mixed, so why is the potential for mixing so important? They answer based on the words of Rabbi Zeira, that it must be eligible for mixing (anything eligible for mixing, the lack of mixing does not invalidate it; but anything not eligible for mixing, the lack of mixing invalidates it).

The Gemara raises a difficulty from the laws of pigul against the principle that "anything ready to be sprinkled is considered as if it were already sprinkled," which implies viewing the act of sprinkling the blood as having already occurred. After resolving this difficulty, the Gemara presents the position of Rav Ashi, who rejects this principle. However, following a challenge from the laws of meilah (misuse of consecrated property), it is clarified that his statement applies only to the laws of ritual impurity of foods; regarding meilah, conversely, Rav Ashi admits that the principle is valid, and the meat is released from the status of meilah the moment it is ready for sprinkling.

Subsequently, another difficulty is raised against Rav Ashi from Rabbi Yosi's ruling regarding the meat of an asham talui, as Rabbi Yosi - according to Rava's understanding - agrees with Rabbi Shimon that "anything standing to be sprinkled is considered as if it were already sprinkled." This difficulty is resolved by providing an alternative explanation for Rabbi Yosi's position that does not rely on this principle. Additionally, Rav Ashi challenges the opposing view, and this difficulty is also resolved.

The Mishna discusses the laws of deviations in meal-offering vows, detailing the law for cases where an individual vowed or pledged a specific type of mincha but brought a different type instead.

The Gemara cites Vayikra 27:11 to teach that blemished animals are called impure. Although the verse refers to "impure animals," there is a different verse (Vayikra 27:27) that explains that impure animals be redeemed; therefore, the first verse must refer specifically to blemished animals.

Shmuel maintains that items consecrated for their value can be redeemed even if they are unblemished. Two difficulties are raised against Shmuel - one by Rav Huna bar Manoach from our Mishna and another by Rav Papa from a braita. Both are resolved by distinguishing between common items and rare items suitable for Temple use; the Sages prohibited the redemption of rare items to avoid a shortage in the Temple.

Several rabbis disagree with Shmuel, holding that items dedicated for their value cannot be redeemed if they are pure. There are two versions of Rabbi Oshaya's position regarding whether he agreed with Shmuel. A difficulty is raised against the version that he permitted their redemption, but it is ultimately resolved.

The Mishna states that when Yom Kippur fell on a Friday, preventing the meat from being cooked, the Babylonians would eat the goat sin offering raw. Rabbi Yochanan clarifies that these people were actually Alexandrians, but they were called Babylonians due to a general dislike of the Babylonians.

The Mishna discusses various errors that can occur while setting up the showbread and the frankincense, such as placing one or both on the wrong day or burning the frankincense at the incorrect time. For each scenario, the text explores the resulting legal status and the solution, if there is one.

A Mishna from Tractate Yoma mentions a case where the Tamid offering was brought too early and had to be burned because it was disqualified. A braita applies this same rule to a mincha offering where the kemitza was taken at night. This raises a question: if sanctified vessels do not normally sanctify their contents at night when offerings cannot be brought, why is the mincha disqualified? To resolve this, it is explained that the offering is sanctified enough to be disqualified even if it is not sanctified for the altar. However, Rabbi Zeira raises a difficulty from our Mishna, noting that when the bread is placed too early, it is not sanctified enough to be disqualified and can remain on the table for extra days. Raba resolves this by distinguishing between an act performed the night before it is due and an act performed several days early. Yet, this distinction still faces issues with the Mishna's case, as the bread should theoretically become sanctified on Friday night and be disqualified by the next Shabbat morning. Ultimately, two resolutions are offered to address this difficulty.

The Mishna outlines how many days after baking the two loaves and the showbread may be eaten. Different scenarios are presented based on whether festivals fall before or after Shabbat, since these loaves cannot typically be baked on Shabbat or a festival. Rabbi Shimon disagrees with this, permitting the baking on a festival though not on Shabbat.

Items whose value is sanctified can be redeemed whether they are ritually pure or impure. However, items sanctified within a sacred vessel possess inherent sanctity and cannot be redeemed even if they become impure. The only exception to this rule is a blemished animal, which retains the possibility of being redeemed despite its status.

The Gemara raises a difficulty regarding the opinion that the Table (Shulchan) was positioned in an east-west orientation. It resolves this by explaining that the Table crafted by Moses was not placed centrally between the other rows of tables, but rather stood on the western side, close to the Parochet, not in between the others. Regarding the ten Tables and ten Menoras added by King Solomon, there is a Tannaic dispute: were they purely decorative - with only the one from Moshe's time being used for the service - or were the lamps lit and the bread arranged on all of them?

In addition to the main Table, two other tables stood in the Ulam (the Entrance Hall) to serve as transition stations for the showbread. One was made of marble (or silver), where the bread was placed before being brought into the Sanctuary, and the other was made of gold, where the bread was placed upon its removal. This distinction is based on the halakhic principle "ma'alin b'kodesh v'lo moridin" (one ascends in holiness but does not descend). Since the bread had already been on a golden table inside the Sanctuary, it could not be placed on a table of lesser value when being taken out. The Gemara finds support for this concept in the fact that the broken Tablets were placed in the Ark also. This leads to a discussion on the importance of preserving one's Torah learning and the gravity of forgetting it, while emphasizing that one must still honor a Torah scholar who has forgotten his learning due to circumstances beyond his control.

The Mishna brings a tannaitic debate about how the bread was replaced each week, based on how each opinion understands the word "tamid" (continually) regarding the showbread. This triggers a fundamental debate regarding the mitzvah of Torah study and the verse, "This book of the Torah shall not depart (lo yamush) from your mouth." While some view this as a mandate to toil in Torah at every available moment, Rabbi Yochanan suggests that even a person who recites the Shema in the morning and evening has fulfilled "lo yamush." For such an individual, it is considered as if they had occupied themselves with Torah day and night.
