Rambam - Sefer HaMitzvos: Positive Mitzvot 102, 103: Positive Mitzvot 102, 103

Positive Mitzvah 102: "Tzara'at" Impurity Affecting Clothes
Leviticus 13:47 "The garment in which there is a plague of Tzara'at..."

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.

Positive Mitzvah 103: "Tzara'at" Impurity in Houses
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.

The Baal Shem Tov taught that in the heavenly court there is no one who can judge you for what you have done in your life on earth. So this is what they do: They show you someone's life -- all the achievements and all the failures, all the right decisions and all the wrongdoings -- and then they ask you, "So what should we do with this somebody?" And you give your verdict. Which they accept. And then they tell you that this somebody was you. Of course, those who tend to judge others favorably have a decided advantage.
Better get in the habit now.
