Exodus 20:14 Thou shalt not commit adultery.
- The punishment prescribed in Leviticus is death. Most modern cultures would frown on such an extreme punishment.
- The reason for this rule was to preserve male bloodlines and male power without needing to guess the paternity of children.
In United States Law
The 7th commandment is not a part of U.S. Law. There is no federal law against the practice of adultery. Many still consider it immoral (religious or not), but the only laws prohibiting it are local or state laws that are rarely enforced. Some have made the argument that such a federal edict would be unconstitutional.
