Genesis 28:6-9

6Now Esau saw that Isaac had blessed Jacob and sent him away to Paddan-aram to take to himself a wife from there, and that when he blessed him he charged him, saying, “1You shall not take a wife from the daughters of Canaan,” 7and that Jacob had obeyed his father and his mother and had gone to Paddan-aram. 8So Esau saw that 2the daughters of Canaan displeased 3his father Isaac; 9and Esau went to Ishmael, and 4married, 5besides the wives that he had, Mahalath the daughter of Ishmael, Abraham’s son, the sister of Nebaioth.
