I've been answering questions about Mormon Doctrine on Yahoo Answers and the "Law of Sarah" has been mentioned a couple of times that I've seen. What is the Law of Abraham and what is the Law of Sarah "Law of Sarah" on lds.org https://www.lds.org/search?lang=eng&query=%22Law+of+Sarah%22 Does the Law of Abraham mean that it was OK to have more than one wife and did the law of Sarah mean that the first wife would have to give permission for a man to take a second wife? Is this what the Law of Sarah means?
