I got another for you.
When Aaron and Miriam challenged Moses they gave a public explanation but Scripture says that they really did so because Moses had married a Cushite, which would be a black woman.
Here I think the punishment given for this is interesting. While I would argue that Aaron was protected by his office (a skin disease would have disqualified him as a serving priest), Miriam was not.
Her punishment was to literally be white for a time.
Why Was Miriam Punished So Harshly?
