BabylonianTalmud, Baba Metzia 83a

Some porters working for Raba bar bar Hanan broke a jug of wine. He seized their clothes. They came before Rav, and Rav said to Raba bar bar Hanan, “Give them their clothing.” Raba bar bar Hanan said to him, “Is this the law?” Rav said, “Yes, because of the principle ‘You should walk in the ways of the good,’ (Proverbs 2:20).” He gave them back their clothes. They said to him, “We are poor, and we troubled ourselves to work all day and we are needy—do we receive nothing?” Immediately Rav said to Raba bar bar Hanan, “Go, give them their wages.” He said to Rav, “Is this the law?” Rav said, “Yes—‘you should keep the ways of the righteous’ (Proverbs 2:20).” [Jill Jacobs translation]
