Rabbi Beivai concludes: And that man, i.e., I, relies on a baker. Therefore, my mind is not sufficiently settled to answer the question properly.

The Gemara asks: What conclusion was reached about this question? Rav Yosef said: Rabbi Yehuda was the halakhic decisor of the house of the Nasi, and he instructed them according to his tradition that the blood of an animal carcass is impure.

As we learned in a baraita: Rabbi Yehuda says that six matters are among the leniencies of Beit Shammai and among the stringencies of Beit Hillel. They include the blood of a carcass, which Beit Shammai deem ritually pure, as in their opinion only the flesh of a carcass imparts impurity; and Beit Hillel deem it ritually impure. Rabbi Yosei, son of Rabbi Yehuda, said: Even when Beit Hillel deemed it impure, they deemed it impure only when it is in the quantity of at least a quarter-log, since that amount, were it to congeal, could constitute an olive-bulk, which is the minimum amount of the flesh of a carcass that is deemed impure.

MISHNA: One does not pledge a libation of one log, two log, or five log of wine, because there are no existing libations with those measures of wine. But one pledges a libation of three log, which is the measure of wine brought with a lamb, or four log, which is the measure of wine brought with a ram, or six log, which is the measure of wine brought with a bull. And one may pledge a libation of six log and beyond, as any greater amount can be composed of combinations of these three.

GEMARA: A dilemma was raised before the Sages: Is there a fixed amount for libations, in that when one vows to bring a certain number of log of wine they are not offered separately, or is there no fixed amount for libations, and it is permitted to divide them and offer them in smaller amounts?

The Gemara clarifies: What are the circumstances? It is a case where he brought five log of wine. If you say that there is no fixed amount for libations, then he removes and offers four of them, as those are suitable for the libations of a ram, and the other log, which is not of sufficient volume, is allocated for communal gift offerings. Either it itself is offered, or it is redeemed and the money is used to buy offerings for the repletion of the altar, i.e., for times when the altar is idle. But if you say that there is a fixed amount for libations and the wine may not be divided and offered separately, then it is not offered itself or redeemed with money and offered until he adds to the existing measurement such that the total number of log may be offered as an independent libation.

What is the halakha? Abaye said: Come and hear the answer from a mishna (Shekalim 6:5): There were six collection horns for communal gift offerings, and we say: For what were they designated? They were designated for funds left over from the purchase of sin offerings, for funds left over from the purchase of guilt offerings, for funds left over from the purchase of a guilt offering of a nazirite, for funds left over from the purchase of the guilt offering of a leper, for funds left over from the purchase of pairs of birds, and for funds left over from the purchase of the meal offering of a sinner.

And if it is so that there is no fixed amount for libations, and if one vowed to bring five log then four are offered as a ram’s libation and the fifth can be redeemed and its money used for a communal gift offering, then let them institute an additional collection horn in the Temple for funds left over from the purchase of libations.

The Gemara responds: These six horns are dedicated to funds that go to communal gift offerings, and these log of wine left over from libations are common, so there is no need to store them, since it is possible that the libation of this person will be combined with the libation of another person together in order to reach the desired amount, and then it is offered immediately. Therefore, no additional horn was necessary for the money from the redemption of libations.

Rava said: Come and hear a resolution to the dilemma from a baraita: The Torah states with regard to libations: “All that are home born shall do these things in this manner, in presenting an offering made by fire, of a pleasing aroma to the Lord” (Numbers 15:13). As this verse is superfluous, the various terms in it are used to derive halakhot. The term “home born” teaches that one may pledge libations even when they are not sacrificed together with an offering. And how much is the minimum volume that is offered? Three log, which is the smallest measurement of a libation in the Torah, i.e., the libation that is offered with a lamb.

And from where is it derived that if one desires to add to this amount he may add? The verse states with regard to libations associated with the additional offerings for the New Moon: “And their libations: Half a hin of wine shall be for the bull, and one-third of a hin for the ram, and one-quarter of a hin for the lamb” (Numbers 28:14). From the superfluous “shall be” one may understand that there are others, and derive that independent libations may also be brought. Can one decrease the amount of wine in a libation to less than three log? The verse states: “All that are home born shall do these things, in this manner” (Numbers 15:13), i.e., one may not bring less than three log of wine.

The Gemara clarifies: What does the baraita mean when it says that one may add to the minimum of three log for an independent libation? If we say it means that it is permitted to offer four or six log, then what is different about three log that it was specified? It is because it is suitable for the libations of a lamb. If so, then four or six log are also suitable, as four log is offered as the libation for a ram and six log is offered as the libation for a bull. Rather, in saying that one may add, isn’t the baraita referring to five log of wine, despite the fact that it is not a measurement used with any of the offerings? And learn from this baraita that there is no fixed amount for libations. The Gemara affirms: Indeed, learn from the baraita that this is so.

Rav Ashi said: But didn’t we learn this in the mishna: One does not pledge a libation of one log, two log, or five log of wine? Rav Ashi continues: In phrasing the mishna in this manner, the tanna teaches that the status of five log is similar to the status of two log: Just as two log are not suitable at all to be offered independently, so too, five log are also not suitable at all to offer, as there are no libations of this size. This demonstrates that there is a fixed amount to libations, and one may not divide them into two.

The Gemara responds: Are the cases comparable? This, two log, is as it is, and that, five log, is as it is, and there is no reason to compare them. Four of the five log are offered, with the fifth allocated for a communal gift offering.

Abaye said: If you say that there is no fixed amount for libations, then there is no fixed amount for libations, and no further discussion is necessary. If you say that there is a fixed amount for libations, then the halakha of up to ten log of wine is obvious to me. One log, two log, or five log may not be brought, since these amounts are not offered as standard libations, but three, four, or six log are brought, as their amount is equivalent to those of standard libations. Between six and ten log may also be brought, since these amounts can be composed of a combination of the various wine libations. With regard to eleven log,
