The Mishnah taught that some viewed the people of Sodom as embracing a philosophy of "what's mine is mine." The Mishnah taught that there are four types of people: (1) One who says: "What's mine is mine, and what's yours is yours"; this is a neutral type, some say this was the type of Sodom. (2) One who says: "What's mine is yours, and what's yours is mine"; this is an unlearned person. (3) One who says: "What's mine is yours, and what's yours is yours"; this is a pious person. And (4) one who says: "What's mine is mine, and what's yours is mine;" this is a wicked person.
