Q & A: Joshua Marries Rahab (Redux)

By Rabbi Yaakov Klass

Question: I recently attended a lecture where the speaker discussed great Jewish women in history. He specifically singled out the biblical heroine Rahab who, he said, married the great leader and prophet Joshua. I had previously heard that Rahab was a woman of ill repute, a harlot, who surely was not suitable for a righteous person like Joshua. Also, when Rahab is mentioned (Joshua ch. 2), there is no indication that she married Joshua. How do we know it? Sandy Hart
