Leviticus 14:34 "A plague of Tzara'at in a house"

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.
