(1.) The daughter of Ishmael, the last of Esau's three wives (Genesis 36:3, 4, 13), from whose son Reuel four tribes of the Edomites sprung. She is also called Mahalath (Genesis 28:9). It is noticeable that Esau's three wives receive different names in the genealogical table of the Edomites (Genesis 36) from those given to them in the history (Genesis 26:34; 28:9).
(2.) A daughter of Solomon, and wife of Ahimaaz, one of his officers (1 Kings 4:15).
