This study investigates how the Rabbis handled the Book of Chronicles. Among several issues, it shows that the Rabbis tried to reconcile the intermarriages mentioned in genealogical lists in Chronicles with the opposition to intermarriage stated in Ezra-Nehemiah. This is apparent because the baraita quoted in b. B. Bat. 15a and the Gemara following it attribute the composition of Chronicles to Ezra and Nehemiah. Ezra composed at least some of the lists, including the intermarriages mentioned there, because those intermarriages were acceptable under certain conditions.
