Midrasz do Przysłów 2:20

(Fol. 83) There were carriers who broke a barrel of wine belonging to Rabha b. b. Chana, while in his service, and he took their garments for the damage caused; and they came to complain before Rab, who commanded Rabba b. b. Chana to return their garments. And when the latter questioned him: "Does the law prescribe so?" he answered: "Yea; (Prov. 2, 20) In order that thou mayest walk in the way of good men." Rabba b. b. Chana did so. The carriers, however, complained again: "We are poor, we were working the whole day, we are hungry and have nothing to eat." And Rab told Rabba that he must pay them for their labor. And he asked again: "Is so the law?" And he answered: "Yea; (Ib., ib.) And observe the path of the righteous."
