The Mishnah taught that an etrog that is stolen or withered is invalid. If the larger part of it is covered with scars, or if its nipple is removed, if it is peeled, split, perforated, so that any part is missing, it is invalid. If only its lesser part is covered with scars, if its stalk was missing, or if it is perforated but nothing of it is missing, it is valid. A dark-colored etrog is invalid. If it is green as a leek, Rabbi Meir declares it valid and Rabbi Judah declares it invalid. Rabbi Meir taught that the minimum size of an etrog is that of a nut. Rabbi Judah taught that it is that of an egg. Rabbi Judah taught that the maximum size is such that two can be held in one hand. Rabbi Jose said even one that can be hold only in both hands.
