the bible is just a record of phrophets. not the spoken word of god. as well, the writers of the bible put there own proseptive of things in, so the bible, is not truely somthing you should follow. its more just a gideline. As well, it says in Leviticas (spelling) that law should be changed every two hundred years, that its not permenet and should morph with time.
""The New Law of Righteousness," that there "shall be no buying or selling, no fairs nor markets, but the whole earth shall be a common treasury for every man," and "there shall be none Lord over others, but every one shall be a Lord of himself.""
