Genesis 28:6-9

Young's Literal Translation

⁶ And Esau seeth that Isaac hath blessed Jacob, and hath sent him to Padan-Aram to take to himself from thence a wife -- in his blessing him that he layeth a charge upon him, saying, Thou dost not take a wife from the daughters of Canaan --

⁷ that Jacob hearkeneth unto his father and unto his mother, and goeth to Padan-Aram --

⁸ and Esau seeth that the daughters of Canaan are evil in the eyes of Isaac his father,

⁹ and Esau goeth unto Ishmael, and taketh Mahalath, daughter of Ishmael, Abraham's son, sister of Nebajoth, unto his wives, to himself, for a wife.
