Illustrations paragraphs 1, 2

1. If Levi sees that Reuven wants to make a business partnership with Shimon and Reuven does not know Shimon, and Levi well knows that due to his evil nature Shimon does not care about other people’s money, Levi should warn Reuven to avoid the partnership. Here too, he should observe all the conditions of the laws of rechilus.
2. If Reuven already made the partnership due to not knowing Shimon, it depends. If Levi knows that Reuven will not believe him but only be careful to not lose money through the partnership with Shimon, Levi must tell him on condition that the conditions of the laws of rechilus are met. But if Levi sees that Reuven will believe him and cause Shimon to suffer a real loss, such as Reuven annulling the partnership or causing other damages, Levi may not tell Reuven.
