This is carnal thinking to a "T." He had two wives already, Hittite women. (Hamidic—they are of the family of Ham.) Then he decided, "Okay, since Isaac and Rebecca have blessed Jacob for going and getting a wife from our family, I will get another wife, also from our family." So, who does he go to? Rather than go back to Padan Aram where his uncle was living, he goes to Ishmael, the son of a concubine, and gets a daughter from him. A third wife. Just adding problem upon problem. He should have had one wife, but he ended up with three because he was jealous of his brother and his relationship with his father and mother.
Everything that we see about Esau shows that he was a typical man of the flesh. If you would go back to Hebrews 12:14-17 you will find that Paul calls him, "an immoral, and profane person" because that is all that he ever thought about—immoral things and profane things—meaning "far from God" ("Far from the Temple" is the exact definition of "profane" in the Greek). But he did not think about God's purposes because he was entirely caught up in the flesh.
