Babylonian Talmud, Brachot 5b

Once, four hundred jars of wine belonging to Rav Huna turned sour. Rav Yehudah, the brother of Rav Sala the Pious, and the other scholars - some say Rav Adda ben Ahava and the other scholars - went to visit Rav Huna and said to him: The master ought to examine his actions. Rav Huna said to them: Am I suspect in your eyes? They replied: Is the Holy One, blessed be God, suspect of punishing without justice? Rav Huna said to them: If somebody has heard of anything against me, let them speak out. They replied: We have heard that the master does not give his tenant his lawful share in the vine twigs [i.e. fair wages for his work.] He replied:Does he leave me any? He [the tenant farmer] steals them all! They said to him: That is exactly what people say: If you steal from a thief you also have a taste of it! He said to them: I pledge myself to give it to him in the future. Some report that thereupon the vinegar became wine again; others that the vinegar went up so high in value that it was sold for the same price as wine. [Translation by Uri L’Tzedek.
