The bible? A fairly arbitrary collection of human writing, human editing and human translation. It exists in many versions with much repetition and a multitude of differences. I can't read Aramaic, know only a very few words of Hebrew and what Ancient Greek I did know is extremely rusty so I'm always a little sceptical about "what the bible says".
From translations it does appear that there are scores of rules about what you can and cannot eat, sacrifices, diseases, agriculture, animal husbandry, slavery, death, inheritance, idolatry, worship and festivals – among other things. There is very little about sexual matters, although sex – hetero and homo – seems to be a preoccupation among the many sects of Christianity from fundamentalist evangelicals to Catholic cardinals. Weird.
