(Mishnah): If a man married four women and he died, the first receives her Kesuvah before the second; the second before the third, and the third before the fourth. The first woman must swear to the second (that she did not already receive her Kesuvah), the second to the third, and the third to the fourth. The fourth receives her Kesuvah without swearing;

Ben Nanas says, does she profit because she is last?! Rather, also she does not collect without swearing.

If all the Kesuvos have the same date, whichever comes first, even by an hour, collects first. In Yerushalayim they used to write the hour of the day.

If all have the same hour and there is only 100 in the estate, they share it equally.

(Gemara - R. Avuna citing R. Shmuel): According to Ben Nanas, if there is one document against many buyers, all divide (pay it) equally.

Question (R. Akiva (the Amora), to R. Mana): Does R. Shmuel's teaching not argue with Shmuel, who said that Shuchda d'Dainei applies to two documents on one field. Beis Din decide for whichever one they want. And here he says so?!

Answer (R. Mana): Does not [Shmuel] discuss two documents (then, we can say that he preferred to give or sell to one of them). Did he discuss one document?! Here, we discuss one document.

Rebuttal: Did he not hear that R. Avun, citing Shmuel, said that there is no difference between one document against two fields, or two documents on one field. Whichever Beis Din wants, they decide.

Rebbi conducted regarding Arnona (the king's tithe), Gulgoles (head tax) and Anperos (Nochrim who take property due to an alleged debt) like Ben Nanas' opinion (all buyers pay equally).

(Our Mishnah said that whichever comes first, merited.) This is like the relatives of R. Yosi. They bought fields from Bar Tafkan's family. Bar Tafkan's family married women, and [fraudulently] gave them a prior lien on the fields, and came to contest R. Yosi's relatives;

R. Mana: I know that when you sold these fields, there was no Shibud on them.
