 That law is there to stop those people that just want to sleep with anybody, and do with them what married people do together. It is there to stop men that want to sleep with other men, as if they are women. It is there to stop people that grab other people to make them prisoners and force them to work for no pay. It is there to stop those people that trick other people by lying to them. That law is there to stop all those sorts of bad things that people do if they dont listen to Gods word.
