Positive Mitzvot 102, 103

The impure signs of Tzara'at may even show up on clothes!

Again, it is the priest that determines this impurity. This teaches us that our actions can even cause our own possessions to become affected by this Tzara'at impurity.

The impure signs of Tzara'at may also appear on the walls of a house!

The priest is called to inspect the house and determine the impurity.

When a house is considered marked by this impurity, the stones in the wall must be removed as a step towards purification.

At times, this may prove to be a blessing in disguise!

When the Jewish people entered the land of Israel, they took possession of the homes of the previous tenants - the Canaanites, as HaShem commanded them.

The Canaanites had hidden their treasures behind the walls and upon removing the stones, the Jews discovered these riches.
