The one whose opponent is not trusted to swear, how so? No matter whether [he had falsely sworn] an oath of a testimony, or an oath of deposit, or even a vain oath; [or if] one of them was a dice-player, or one who lends on interest, or [they were] pi-geon flyers, or Sheviis-merchants —- his opponent swears and collects. [If] they were both suspect —- the oath returns to its place; [these are] the words of R' Yose. R' Meir says: They divide.
