Three people that threw [money] into a [combined] purse and some of it was stolen—they bring the rest into the middle and divide it equally. Two people that threw [money] into a purse, this one 100 zuz, that on 200 zuz, and they were occupied in business together—they split the profits equally. If this one bought with his own [money] and that one bought with his own but they got mixed up together—this one takes what is his and that one takes what is his. Three [loan] contracts [owned by one person] that were issued at the same time—the first [debtor] can make the second one swear [that he hasn't already collected his debt since he is concerned lest there not be enough property for him], and the second can make the third one swear. If the second wants to not make the first one swear, the third one can prevent him [since his oath also applies to the third one, who is even more worried that there will not be enough property]. One who has a loan from one person and sold his field to two people [and the field is worth the loan amount], then the creditor wrote to the second one "I have nothing on these things with you"—the second one (sic! should read, "he", i.e. the creditor; see Lieberman) is not able to collect because he relinquished the place that he could have collected from.
