What is implied? A person takes a wallet belonging to a colleague and throws it into the sea, or into a fire, or gives it to a person of force and thus causes it to be lost. The owner of the wallet claims that it was filled with gold coins, while the person who caused the damage says: "I do not know what it contained. Perhaps all it contained was earth or straw."
The person whose property was damaged is entitled to take an oath while holding a sacred article and collect the money he claims, provided he claims articles that we may assume that he owns or that were entrusted to him and would ordinarily be put in a wallet or the like.
If, however, it is not customary to place such articles in such containers, the owner is considered negligent and the person who caused the damage is not held liable.
What is implied? A person grabbed a filled covered leather sack or basket and threw it into the water or burned it. The person whose property was destroyed claimed that it was filled with pearls. His claim is not accepted, and the person who caused the damage is not required to take an oath. For it is not customary to place pearls in baskets or leather sacks.
If, however, the person whose property was damaged seizes property belonging to the person who caused the damage equivalent to the value of his claim, it should not be expropriated from him. Instead, he is required to take an oath that it contained pearls, and then he is able to keep their worth from the goods that he seized. The same laws apply in all analogous situations.
