Menachot 104 - Shabbat April 25, 8 Iyar

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.
