Before you "condemn" someone for lying you should read the whole story. He did marry his sister.
Well..only partially correct. Sarah was actually Abraham's half sister. In another of his entanglements he explained the situation further as being the daughter of his father but not the daughter of his mother. Back to school with you![/quote]
I have grandchildren who have the same dad but different moms. They speak of their siblings with out saying, "This is my half sister." They are not trying to deceive. They don't seem to give it any thought.
