'Mistress' in the Bible

And Hadad findeth grace in the eyes of Pharaoh exceedingly, and he giveth to him a wife, the sister of his own wife, sister of Tahpenes the mistress;

and also Maachah his mother -- he turneth her aside from being mistress, in that she made a horrible thing for a shrine, and Asa cutteth down her horrible thing, and burneth it by the brook Kidron;

And it cometh to pass, after these things, the son of the woman, mistress of the house, hath been sick, and his sickness is very severe till that no breath hath been left in him.
