Genesis 27:11

Aging Isaac, now blind, calls for his elder son Esau to prepare a savory meal so that he may bless him, but Rebekah overhears and conspires with Jacob to obtain the blessing by deception. Disguised in Esau's garments and goatskins on his arms, Jacob brings the meal and receives Isaac's irrevocable blessing of the firstborn. When Esau returns and discovers the trick, he weeps bitterly, receives a lesser blessing, and resolves to kill Jacob, prompting Rebekah to send Jacob away to her brother Laban.
