A man who married two wives and died—the first one has precedence over the second one, and the inheritors [born to] the first one have precedence over the inheritors [born to] the second one. If he divorced the first one, remarried her and wrote for her a new ketubah—the first ketubah of the first one takes precedence over the second and her inheritors; the second one and her inheritors take precedence over the second ketubah of the first one. When does this apply? With the ketubah, but regarding financial support—both [wives] are equal. Wives and daughters are both equal [with regard to their financial support after the father's death].
