And that’s why when tzaraas came upon a man's house, he followed the old Jewish derech of suspecting himself, of blaming himself, of searching. “Maybe I have to remedy this fault and change this wrong habit.” And he discovered; ‘this thing is wrong’ or ‘that thing’ and he became better because of that. Because if a person searches, if he looks hard enough – a lot of people don’t have to look hard at all – he's going to discover a pot of gold.
Now is it true that only because of their sins a misfortune comes? Absolutely not. Because we already learned about how leprosy came upon a house and the purpose was for the owner to discover a chest of gold; sometimes it happens that way. He might discover wealth; diamonds and gold and silver. Wealth is wealth! You can't ridicule wealth!
But the real chest of gold is what we're learning about here. That he becomes better because of that nega on his wall, that he searches out his ways and does teshuva. That's the besurah tovah. That's the real good news – the great wealth of perfection that comes from utilizing misfortune for nachpesah deracheinu, for searching in ourselves.
