Rabbi Yochanan and Reish Lakish disagree about a case where oil was placed on the kometz of a mincha of a sinner, which is not meant to be mixed with oil. Rabbi Yochanan disqualifies it, but Reish Lakish does not, as he holds that the oil should not be mixed with the mincha before the kometz is taken, but the kometz can (and ideally should) be mixed with a little bit of oil. Rabbi Yochanan brings a tannaitic source to raise a difficulty against Reish Lakish's position, but it is resolved.

Rava asks a question about a kometz whose oil (some of it) was absorbed onto a piece of wood. Can both be burned together to ensure that all the oil of the kometz is burned, or would this not be effective as the wood is completely separate from the kometz? Ravina questions Rava as the issue is already known as a debate between Rabbi Yochanan and Reish Lakish. But they explain why the question can be asked according to each.

The Mishna explains what to do in three different cases of mixtures of meal offerings that were at various stages - either two minchas before the kometz was taken, or a kometz with a different mincha where the kometz was not yet taken, or a kometz mixed with the remainder.

Rav Chisda and Rabbi Chanina disagree within Rabbi Yehuda's position of min b'mino (items of the same type) is not nullified, as understood by Rabbi Chiya, that items are considered the same if the status of one can change to be like the other. Rav Chisda says it is determined by the item trying to nullify, and Rabbi Chanina by the item being nullified. The three cases in our Mishna and a fourth source regarding matza are brought as difficulties to one or both of the opinions, but all are resolved.
