Yesterday we discussed the story in Melakhim II chapter 7, which is normally read as the haftara for Shabbat Parashat Metzora. As we mentioned, the Tanakh tells of the four metzoraim who lived outside the city of Shomron when the enemy nation of Aram besieged the city. Rashi (7:3) explains that the four metzoraim dwelled outside the city in observance of the Torah law banishing those stricken with tzara’at from the cities of the Land of Israel.
