Who were the three wives of Esau?

       Bashemath the first from Genesis 26:34, the daughter of Elon the Hittite, and the first of two of Esau's wives. In Genesis 36:2 she is called Adah. She became his wife when he was forty years old and turned out to be a "grief of mind" to Esau's parents, Isaac and Rebekah.
       Tradition has it that Esau had hunted, eaten, and drunk for years with sons of Elon, his wife's brothers, also had sworn, sacrificed, and vowed to their false gods of the fields and the groves. Having outdone her brothers in his debaucheries, Esau finally had brought Bashemath, a Canaanite, and Judith, daughter of Beeri, another Canaanite, into the covenanted camp of his father.
       The record of Bashemath's marriage to Esau comes at a significant place. The next verse begins the story of the blessing and how Jacob obtained it. A long space of years had passed, however, probably about thirty-seven. Esau had had time to repent of his errors and to return to the godly way of life. But he did not. He continued in the path of the godless; and it is probable that this wife was one of the reasons for his turning away from God.
       Bashemath 2 from (Gen. 36:3, 4, 10, 13, 17), a second wife of Esau also bearing the name of Bashemath. She was the daughter of Ishmael and sister of Nebajoth and in Genesis 28:9 her name is given as Mahalath. Esau probably married her after his marriage to the first two Hittite wives recorded in Genesis 26:34. This second Bashemath or Mahalath was the mother of Reuel.
