In the Genesis 26:34–35, Basemath is the name of the first wife of Esau. She was the daughter of Elon the Hittite (Genesis 26:34–35). Because Basemath was a Canaanite, Esau’s marriage to Basemath (as well as to his second wife, Judith) ignored God's wishes that Abraham’s descendants keep themselves separate from the Canaanites in marriage.
