Mishna, Pirkei Avot 5:10

There are four types of character in people: 1) One that says, "Mine is mine, and yours is yours." This is a neutral type; some say this is a Sodom-type of character. 2) One that says, "Mine is yours and yours is mine," is an unlearned person. 3) One that says, "Mine is yours and yours is yours," is a pious person. 4) One that says, "Mine is mine, and yours is mine," is a wicked person.
