When a Kohen performs the kemitza, the presence of a pebble, a grain of salt, or a shard of frankincense within the handful renders the offering invalid. This is because the Torah requires a precise "handful," and these foreign objects either displace the necessary flour (making it "missing"). The Gemara explains the need for the Mishna to bring all these examples. Rava explains that kemitza is performed with all five fingers. Abaye questions this from a braita that explains the need for all five fingers, as can be seen from the name of each of the fingers. The fourth finger is called kemitza, implying that only the three middle fingers are used for kemitza. To resolve this Rava explains that all five fingers are used but not all for the scooping. The kohen extends his three middle fingers over his palm to gather the dough, while simultaneously using his thumb and pinky to level the scoop by wiping away any excess flour protruding from the edges. This ensures the volume is exactly the capacity of his palm. This is one of the most difficult actions to be performed in the Temple, among them melika and chafina.

Rav Papa questions whether non-traditional methods - such as scooping with the fingertips facing down, or in other atypical ways, are valid, ultimately leaving these queries unresolved. He also questions different methods of chafina of the incense that the kohen gadol does on Yom Kippur. Rav Papa and Mar bar Rav Ashi question atypical ways of placing the kometz in the sanctified vessel. All these questions are left unresolved.

If there is too much oil or too little added to the mincha offering it is disqualified. There is a discussion about how much is too much and in what cases does it disqualify. Regarding the frankincense (levona), there is a dispute regarding the minimum amount required for the offering to remain valid. Rabbi Meir holds that a full handful must be present, while Rabbi Yehuda and Rabbi Shimon allow for a reduction to two granules or even a single granule, respectively. There is a debate about whether these three opinions are only relevant in frankincense brought as a supplement to a meal offering or also when the frankincense is brought as its own offering.

The validity of the meal offering is also tied to the kohen's mental intent (machshava). If the kohen intends, while taking the kometz (parallel to the act of slaughtering an animal) to eat the remains or burn the handful of the meal offering or the frankincense outside the Temple courtyard, the offering is disqualified but does not carry the penalty of karet. However, if he intends to consume or burn the offering outside its designated timeframe (the following day), the offering becomes pigul. This status not only invalidates the sacrifice but also makes anyone who eats it liable for the punishment of karet.

The section of the Torah concerning the metzora (leper) details two distinct tracks for sacrifices: one for the wealthy, who bring three animal offerings, and a modified track for the poor. The purification process involves pouring oil into the kohen's left hand, followed by sprinkling it toward the parochet and placing it on the leper's right ear, thumb, and toe. Notably, the text contains several seemingly superfluous phrases in the wealthy leper's section, as well as extensive repetitions in the poor leper's section that could have been simplified with a cross-reference like "as mentioned above."

Rabbi Zeira and Rava offer different explanations for these repetitions. Both scholars derive that the kemitza of the mincha (meal offering) must be performed with the right hand, but they reach this conclusion via different paths. Rabbi Zeira learns it from the fourfold mention of the word "left" in the leper section. In contrast, Rava utilizes a gezeira shava based on the word "right" used in the context of placing oil on the leper's ear, thumb, and toe, applying that requirement to the kemitza.

Reish Lakish teaches a broader principle: whenever the Torah uses the words "finger" (etzba) or "kohen" the service must be performed with the right hand. While the Gemara initially assumes both words must appear together to trigger this requirement, Rava clarifies that either word alone is sufficient. However, following a challenge from Abaye, Rava distinguishes between two scenarios: in cases where the action is essential for atonement, either word indicates the right hand; in cases where the action is not essential for atonement, both words must be present to mandate the right hand.

A difficulty is raised against Rava's explanation based on the position of Rabbi Shimon. To resolve this, the Gemara suggests that Rabbi Shimon requires both words in all instances. Two subsequent challenges to this theory and one is resolved by further refining Rabbi Shimon's position: the appearance of the word "finger" alone necessitates the right hand, but the word "kohen" does not, unless it appears in conjunction with "finger."

If Rava holds that "finger" or "kohen" already serves as an indicator for using the right hand, why did he originally use a gezeira shava to learn this regarding kemitza? The Gemara explains that he requires two separate derivations - one for the act of kemitza itself and another for placing the kometz into a sanctified vessel. This theory is again questioned in light of Rabbi Shimon's view that the kometz does not require a vessel at all. Ultimately, the Gemara concludes the gezeira shava (for Rabbi Shimon) is necessary for the sinner's meal offering; otherwise, one might have thought it could be performed with the left hand, as, according to Rabbi Shimon himself, this specific offering is not intended to be mehudar (ornate or distinguished).

Earlier, Rabbi Yochanan employed the principle that something that takes place in the Temple courtyard can obviously also be performed in the Sanctuary (such as slaughtering the peace offering), as the Sanctuary is more sanctified. However, in a different situation, a verse is needed to derive that items permitted to be eaten in the courtyard can also be eaten in the Sanctuary (in unique circumstances). Why was a verse needed if the principle of Rabbi Yochanan could have been used? The Gemara answers by distinguishing between a ritual (slaughtering) and eating.

There are three debates between Rabbi Yochanan and Reish Lakish regarding mincha (meal) offerings. First, if they are mixed outside the Temple courtyard, are they disqualified? Second, if the mincha batter is missing some part before the kemitza (handful) is taken, can it be refilled? Third, if the remainder is missing a part after the kometz is taken, can the kemitza be burned? In each debate, the Gemara explains the reasoning behind each approach. In all three instances, a support is brought for Rabbi Yochanan or a difficulty is raised against Reish Lakish's position which remains unanswered. In the third debate, a difficulty is also raised against Rabbi Yochanan's position but is resolved.

The Mishna ruled that if the kohen performs the kemitza with his left hand, it is disqualified. The source for this is that when explaining the process of the leper's purification, the text specifically says "left hand." Since the text regarding the mincha offering simply says "hand" without the word "left," we can assume that if an action can be done with the left, the Torah will specifically say "left"; conversely, if it appears without specifying a hand, it must refer to the right hand. The Gemara questions this drasha, suggesting that perhaps the verse is not intended to teach about other mentions of the word "hand." However, after pointing out that the phrase "left hand" appears four times in the section on the leper's purification, it becomes clear that the repetition comes to teach that in other cases where the word "hand" is mentioned, it refers exclusively to the right hand.

Rabbi Eliezer holds that when the Kohen accepts the blood from a sacrifice into a sanctified vessel, there must be enough collected in that single bowl to be used for placing the blood on the altar. If one collects some blood in one bowl and some in another, and later mixes them together before performing the placements, the blood is not sanctified.

The Gemara suggests that Rabbi Eliezer contradicts himself, as regarding the Kohen Gadol's griddle-cake offering (minchat chavitin), he holds that it is sanctified even if placed in two separate bowls. To resolve this, the Gemara first suggests that perhaps Rabbi Eliezer does not derive one law from another—specifically, a mincha offering from blood. However, this is rejected because Rabbi Eliezer does derive laws for a mincha from the bowls of frankincense of the Showbread. In conclusion, the Gemara distinguishes between learning a mincha offering from another mincha-style offering and learning a mincha offering from an animal sacrifice (blood).

Rabbi Yochanan disagrees with Rabbi Elazar regarding the minchat chavitin and rules that it is not sanctified if placed in the vessel in parts. Rabbi Acha brings the source in the Torah for his prohibition, and the Gemara brings two braitot that support his opinion and contradict Rabbi Elazar's position.

Rabbi Yochanan's position regarding the Kohen Gadol's griddle-cake offering (minchat chavitin) is questioned in light of a position he holds against Rav in a case of a regular mincha offering that is sanctified even before the person completely filled the vessel with the fine flour. Why does he differentiate between the cases?

The Gemara then asks about Rav, who disagrees with Rabbi Yochanan and requires the vessel to be filled: would he hold like Rabbi Yochanan or Rabbi Elazar regarding the minchat chavitin offering? They conclude that since he derives one item from another (on a different mincha-related issue), he would derive from the minchat chavitin to here, and therefore he must hold like Rabbi Yochanan by the minchat chavitin and requires it to be complete to sanctify.

Since the Gemara mentions a different mincha-related issue where Rav derives one thing from another, they quote that source in its entirety and delve into his debate with Rabbi Chanina about mincha offerings where not all the parts were added yet to the bowl – are they sanctified without everything being there?

At the beginning of the daf, Rabbi Elazar had made a comparison of taking the kometz from a mincha in the Sanctuary, which is permitted as it is derived from the bowls of frankincense from the Showbread. Rabbi Yirmia raises a difficulty against this from a braita, but the drasha in that braita is reinterpreted to fit with Rabbi Elazar's ruling.

According to Yosi ben Yasiyan and Rabbi Yehuda the Baker, ben Beteira permits returning a kometz taken in a disqualified manner to the original dough, provided it has not yet been placed in a sanctified vessel. Rav Nachman challenges this ruling: if taking the kometz is a significant ritual, the act should be irreversible; if it is not, placing it in a sanctified vessel should be meaningless. Rav Nachman resolves this by explaining that while taking the kometz is indeed a ritual act, it is not complete until the kometz is placed in the vessel.

If so, the Gemara objects, returning the kometz to the original dough - which is also held in a sanctified vessel - should complete the act and permanently disqualify it. This difficulty is answered in two ways. Rabbi Yochanan answers that one can derive a principle from here: sanctified vessels only sanctify items if they are placed inside with intent to sanctify. The Gemara questions this assumption, noting that it implies one could intentionally sanctify disqualified items; yet, Rabbi Yochanan previously answered Reish Lakish that disqualified items cannot be sanctified for the altar by being placed in a sanctified vessel. This contradiction is resolved by distinguishing between sanctifying an item to permit it to be offered on the altar (which is not effective) and sanctifying an item merely to disqualify it (which is effective).

Rav Amram answers the original question by qualifying the case to when the kometz is returned to a heaping bowl. As a sanctified vessel only sanctifies what is within the walls of the vessel, the kometz is not sanctified to be disqualified when placed back in the original vessel. After raising a difficulty regarding the reality of this case, his answer is partially modified to a level bowl, not heaping.

Rabbi Yirmia tells Rabbi Zeira that he derives from the fact that they did not suggest returning it to the vessel when it was on the ground, that the actions of kemitza do not need to be performed while a kohen is holding the vessel in his hands. Rabbi Zeira points out that this was an issue raised by Rav Nachman to Avimi, who explained that the kohen indeed needs to be holding the vessel.

Rav Sheshet disagrees, holding that the Kohen does not need to be holding the vessel for all the actions of kemitza. He derives this from the laws of the Showbread, as he understands from a Mishna that the kohanim did not hold up the Table when the Showbread and bowls of frankincense was switched at the end of each week. Rav brings a third position: The first two actions - placing the dough in the bowl and taking the kemitza - do not require the kohen to be holding the vessel, but the kometz must be placed in a vessel held by a kohen, as it is parallel to accepting the blood of a sacrifice.

Rav Sheisha brings a fifth explanation of an ambiguous line in the braita brought on Menachot 5b, "If you had raised a difficulty on the logical argument." As in all the previous explanations, also this one is rejected.

Rav Ashi suggests that one could knock out the logical argument from the beginning as perhaps one could not even bring a kal v'chomer from blemished animals as they have a stringency. This suggestion of Rav Ashi is modified a few times and ultimately his explanation is that if one were to make a kal v'chomer with both blemished animals and ones born not through natural childbirth, one could reject that kal v'chomer as they both have a stringency that is not in a treifa as they have noticeable issues, whereas a treifa is not necessarily noticeable.

The braita concluded that the source for a treifa not being able to be offered on the altar is derived from "from the cattle." However, two other verses also are used to exclude a treifa. Why are all three verses necessary?

The Mishna rules that any meal offering that the kemitza is done by a non-kohen, onen, impure person, etc. (i.e. not in the proper manner), is disqualified. Ben Beteira disagrees and explains that if it was done with the left hand, one returns the kometz to the pile and redoes it with the right hand. If a kohen took the kemitza but there was something else in there like a pebble or frankincense, it is invalid as the kemitza must be a precise handful, no more and no less.

The Gemara first questions the language of the Mishna – why does it list the mincha offering brought for a sin together separately from the others. The answer is that the Mishna is highlighting that even according to Rabbi Shimon who holds that a sinner's offering should not be glorious, it still needs to be done properly. Even though in Zevachim, the parallel Mishna relating to sacrifices does not single out the sin offering, the Gemara explains why there was no need there to explain it according to Rabbi Shimon, but there was a need here.

Rav explains that any disqualification can be fixed by redoing it. At first, they question Rav's ruling in light of the rabbis' position in the Mishna, but then they explain that Rav holds like ben Beteira and is coming to explain that even though ben Beteira only mentioned the disqualification of the left hand in the Mishna, his ruling applies for all disqualifications. The Gemara raises a difficulty on this from tannaitic sources that show that this was clear even before Rav made his statement. To resolve the difficulty, they bring a different explanation – that Rav was pointing out that ben Beteira permits it to be redone even if the kometz was placed in a sanctified vessel, which disagrees with a tannaitic opinion that it can be fixed only if it wasn't yet placed in a sanctified vessel. According to others, Rav is coming to teach the exact opposite and to show that he agrees with the tannaitic opinion that it can only be fixed if it was not yet placed in the vessel.

There are three different opinions about the status of the mincha offering of the omer that is offered for the sake of a different offering. Rav says it is completely disqualified, Reish Lakish holds it is valid, but the obligation to bring the mincha is not fulfilled and a new one must be brought, and Rava holds that it is valid and the obligation is fulfilled.

Rav added another disqualified case to the list – a guilt offering of the nazir and leper. After a discussion about why he would distinguish between that guilt offering and a guilt offering for theft or misuse of consecrated property, the Gemara brings a braita that clearly contradicts Rav as it says explicitly that a guilt offering of a leper offered for the sake of the wrong sacrifice is brought on the altar.

A difficulty is raised against Reish Lakish's position. If the omer offering that is brought for the sake of the wrong offering does not fulfill its obligation, how can it be offered on the altar as one can only offer on the altar items that can be eaten by Jews and this is an offering from the chadash (new grain) and the chadash is only permitted with the omer offering. Two answers are brought to resolve this difficulty. The first answer is brought by Rav Ada bar Ahava who suggests that since it will be permitted later that day, when the omer offering is brought correctly, it is not considered a forbidden item. Three difficulties are raised against Rav Ada, two are resolved but the last one is not. Rav Papa offers an alternative answer – that the actual omer offering does not permit the chadash, but the illumination of the eastern horizon on that day permits it (16th of Nisan).

This suggestion of Rav Papa is further supported by claiming that Rabbi Yochanan and Reish Lakish both agreed that the chadash is permitted from that time and not from the offering of the omer, as is derived from a statement of Reish Lakish.

A braita teaches that one can derive from a verse "from the cattle" that a treifa cannot be brought on the altar. However, the braita suggests that it could have been derived by a kal v'chomer, but since one can raise a difficulty against that kal v'chomer, it is derived from a verse. However, it is unclear what the difficulty could have been and the Gemara brings several possible suggestions. But difficulties are raised against each of them.

What was clear to Raba on one hand and Rava on the other - regarding how to understand Rabbi Shimon's words and whether a noticeably incorrect intent (machshava nikeret) disqualifies or not - was not clear to Rav Hoshaya, who deliberated on how to interpret Rabbi Shimon's position. The Gemara explains why he did not accept the opinions of Raba, Rava, or Rav Ashi as a sufficient explanation for his doubt.

The Mishna mentions two exceptions to the rule of a meal offering (mincha) that was perfomed for the wrong purpose (where the offering is valid but the owner has not fulfilled their obligation): the sinner's meal offering (minchat choteh) and the jealousy offering of a Sotah (minchat kenaot) are completely disqualified if perfomed for the wrong purpose (shelo lishmah). What is the source for this? The Gemara initially presents a derivation for each of them from the sin offering (chatat), but after rejecting these derivations due to a difficulty regarding the guilt offering (asham), it brings a different exposition based on a gezeirah shava (verbal analogy) to both of these meal offerings.

Rav adds the Omer meal offering to this list, stating that if it was performed for the wrong purpose, it is disqualified because it is intended to permit the consumption of the "new grain" (chadash), and if brought for the wrong purpose, it fails to permit it and is useless. He says the same regarding the nazirite's guilt offering (asham nazir) and the leper's guilt offering (asham metzora). If so, why are this meal offering and these sacrifices not mentioned in the Mishnayot in Menachot and Zevachim that list those disqualified if they were brought for the wrong purpose? The Gemara answers this question and settles the difficulty.

The Gemara further challenges Rav: if the asham nazir and asham metzora are meant to "enable" (le'hachshir) a status change and fail to do so when brought for the wrong purpose, then the guilt offering for misappropriation (asham me'ilot) and the guilt offering for theft (asham gezeilot) - which are meant to "atone" (le'chaper) - likewise fail to atone; why then are they valid if brought for the wrong purpose? Rabbi Yirmiya makes a distinction between offerings that "enable" status (machshirim) and those that "atone" (mechaperim). He brings proof from the laws of sacrifices brought after the death of the owner, specifically citing a Mishna regarding a woman after childbirth (yoledet). Rabbi Yehuda, son of Rabbi Shimon ben Pazi, challenges this distinction (regarding the laws after death) from a Mishna in Nazir, where an enabling sacrifice is indeed brought after death.
