Can't remember where it is, but there is mention that when a woman has her period, she is to be essentially cast out and exciled until she has stopped bleeding. Also, if a man dies, his brother should lay with his wife.

I read a very interesting article awhile back about the bible's take on homosexuality. It basically points out that thanks to poor translation, the Church has been condemning gay people when they really shouldn't be as it's not a sin worthy of spiritual death. I'll try and track it down and post it here.
