[If] one robs another, or borrows from him, or deposits [something] with him in a settled region, he may not return it to him in the wilderness, on condition that he was going out to the wilderness, he may return it to him in the wilderness.

[If] one says to another: “I robbed you,” “You lent me,” [or] “You deposited with me,” ... but I do not know whether I returned [it] to you or whether I did not return [it] to you,“ he is obligated to pay. But if he says to him: “I do not know whether I robbed you,” “whether you lent me,” [or] “whether you deposited with me,” he is exempt from paying.
