Genesis 28:7-9

Amplified Bible

⁷ and that Jacob obeyed his father and his mother and had gone to Paddan-aram. ⁸ So Esau realized that [his two wives] the daughters of Canaan displeased Isaac his father; ⁹ and [to appease his parents] Esau went to [the family of] Ishmael and took as his wife, in addition to the wives he [already] had, Mahalath the daughter of Ishmael, Abraham’s son, the sister of Nebaioth [Ishmael’s firstborn son].
