Rav and Shmuel disagree about how to understand the line in the Mishna regarding an oath of a partial admission: "a claim must be two ma'ah of silver" - is it referring to the amount of the claim - meaning what the claimant's side is demanding or is it referring to the defendant's claim - how much is the defendant denying? There are four attempts to support Rav's understanding from the Mishna and other tannaitic sources, however the first three can be explained according to Shmuel as well.
Two other rulings of Shmuel are brought, including a basic one that if one claims the other owes two different items and the other admits of having one of the items, the defendant takes an oath of partial admission. Two versions are brought about whether Rabbi Yochanan agreed or disagreed with this opinion. Proofs are brought to prove Shmuel's opinion but are proven to be inconclusive. Likewise, those same proofs are brought to disprove the opinion that Rabbi Yochanan disagrees but are rejected in the same way.
