8And after him [i.e. Jephthah], Ibzan of Bethlehem judged Israel. 9 And he had thirty sons, and thirty daughters, whom he sent abroad, and took in thirty daughters from abroad for his sons. And he judged Israel seven years. 10 Then died Ibzan, and was buried at Bethlehem.
However, the Talmud (Bava Batra 91a) asserts that Ibzan is to be identified with Boaz from the Book of Ruth, who lived in the Bethlehem in Judah, and that he consummated his marriage with Ruth on the last night of his life.
