The Asmodeus of the Book of Tobit is hostile to Sarah, Raguel's daughter, (); and slays seven successive husbands on their wedding nights, impeding the sexual consummation of the marriages. He is described as "the worst of demons". When the young Tobias is about to marry her, Asmodeus proposes the same fate for him, but Tobias is enabled, through the counsels of his attendant angel Raphael, to render him innocuous. By placing a fish's heart and liver on red-hot cinders, Tobias produces a smoky vapour that causes the demon to flee to Egypt, where Raphael binds him (). According to some translations Asmodeus is strangled.
