Genesis 28:6-9

American Standard Version

⁶ Now Esau saw that Isaac had blessed Jacob and sent him away to Paddan-aram, to take him a wife from thence; and that as he blessed him he gave him a charge, saying, Thou shalt not take a wife of the daughters of Canaan; ⁷ and that Jacob obeyed his father and his mother, and was gone to Paddan-aram: ⁸ and Esau saw that the daughters of Canaan pleased not Isaac his father; ⁹ and Esau went unto Ishmael, and took, besides the wives that he had, Mahalath the daughter of Ishmael Abraham’s son, the sister of Nebaioth, to be his wife.
