To make the story clear, some Biblical scholars believed that Esau changed names of two wives to the Hebrew to pacify his parents: Genesis 26:34–35 describes Esau's marriage at the age of forty to two Canaanite women: Judith, the daughter of Beeri the Hittite, and Basemath the daughter of Elon the Hittite.
[2] Upon seeing that his brother was blessed and that their father rejected Esau's union to Canaanites, Esau went to the house of his uncle Ishmael and married his cousin,[3] Mahalath the daughter of Ishmael, and sister of Nebaioth.
[4][5] Casting his lot with the Ishmaelites, he was able to drive the Horites out of Mount Seir to settle in that region.
According to some views, Esau is considered to be the progenitor not only of the Edomites but of the Kenizzites and the Amalekites as well.
[6][7] Reuven Chaim Klein summarizes how the various Medieval Jewish commentators broadly provide four interpretations to address the inconsistency between the accounts of Esau's wives in Genesis 26 and Genesis 36:[8] In Midrash and Aggadah we found more context and background of the lives of Esau's wives.
