Genesis 28:6-9 - Esau Marries An Ishmaelite
6 Now Esau saw that Isaac had blessed Jacob and sent him away to Paddan-aram to take a wife from there, and that as he blessed him he directed him, "You must not take a wife from the Canaanite women," 7 and that Jacob had obeyed his father and his mother and gone to Paddan-aram. 8 So when Esau saw that the Canaanite women did not please Isaac his father, 9 Esau went to Ishmael and took as his wife, besides the wives he had, Mahalath the daughter of Ishmael, Abraham's son, the sister of Nebaioth.
