Genesis 26:34

"Esau took his wives of the daughters of Canaan; Adah the daughter of Elon the Hittite, and Aholibamah the daughter of Anah the daughter of Zibeon the Hivite;"

"And thou take of their daughters unto thy sons, and their daughters go a whoring after their gods, and make thy sons go a whoring after their gods."

"And these are the sons of Reuel; Nahath, and Zerah, Shammah, and Mizzah: these were the sons of Bashemath Esau's wife."

"And Aholibamah bare Jeush, and Jaalam, and Korah: these are the sons of Esau, which were born unto him in the land of Canaan."

"Then went Esau unto Ishmael, and took unto the wives which he had Mahalath the daughter of Ishmael Abraham's son, the sister of Nebajoth, to be his wife."

"And I will make thee swear by the LORD, the God of heaven, and the God of the earth, that thou shalt not take a wife unto my son of the daughters of the Canaanites, among whom I dwell:"

"Lest there be any fornicator, or profane person, as Esau, who for one morsel of meat sold his birthright."

"Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband."
