תּלמוד אויף דברים 6:18

Said the Nehardeans, "An evaluation must be returned for up to twelve months of a year." But said Ameimar, "I am from Nehardea and I hold that an evaluation must always be returned." And the law is [that] an evaluation must always be returned, on account of that which is stated (Deuteronomy 6:18), "And you will do the straight and the good."
