Genesis 28:5 (KJV)

And Isaac called Jacob, and blessed him, and charged him, and said unto him, Thou shalt not take a wife of the daughters of Canaan.

Arise, go to Padanaram, to the house of Bethuel thy mother's father; and take thee a wife from thence of the daughers of Laban thy mother's brother.

And God Almighty bless thee, and make thee fruitful, and multiply thee, that thou mayest be a multitude of people;

And give thee the blessing of Abraham, to thee, and to thy seed with thee; that thou mayest inherit the land wherein thou art a stranger, which God gave unto Abraham.

When Esau saw that Isaac had blessed Jacob, and sent him away to Padanaram, to take him a wife from thence; and that as he blessed him he gave him a charge, saying, Thou shalt not take a wife of the daughers of Canaan;

And that Jacob obeyed his father and his mother, and was gone to Padanaram;

And Esau seeing that the daughters of Canaan pleased not Isaac his father;

Then went Esau unto Ishmael, and took unto the wives which he had Mahalath the daughter of Ishmael Abraham's son, the sister of Nebajoth, to be his wife.

And Jacob went out from Beersheba, and went toward Haran.
