Genesis 28:6-9

Leeser(i) 6 And when Esau saw that Isaac had blessed Jacob, and sent him away to Padan-aram, to take himself from there a wife; and in blessing him had given him a charge, saying, Thou shalt not take a wife of the daughters of Canaan; 7 And that Jacob had obeyed his father and his mother, and was gone to Padan-aram: 8 Then saw Esau that the daughters of Canaan were evil in the eyes of Isaac his father; 9 And Esau went unto Ishmael, and took Machalath the daughter of Ishmael, Abraham’s son, the sister of Nebayoth in addition to his wives, to himself as wife.
