Genesis 27:10

And thou shall bring [it] to thy father
For venison; and as if he was Esau that brought it: that he may eat, and that he may bless thee before his death;
to whom she knew by the divine oracle the blessing belonged, ( Genesis 25:23 ) , as well as by virtue of the sale of the birthright to him by his brother, ( Genesis 25:33 ) , and through Esau's forfeiting of it by marrying with the Canaanites, ( Genesis 26:34 ) ; in these her sentiments she was right, but wrong in the ways and means she took to get it for him.
