'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 came to pass after these things, that the son of the woman, the mistress of the house, fell sick; and his sickness was so sore, that there was no breath left in him.
