How does this parallel the concept that each hair has it's own follicle and source of power? Why did the Kohen (priest) want to leave Israel, and how did his wife convince him otherwise, based on his own teaching?

How does this parallel the spiritual disease of egotism and lashon hara (gossip) that precedes the advent of tzara'as? Find out in this week's Parsha Podcast.
