Genesis 27:42

And these words of Esau, her elder son, were told to Rebekah; and she sent and called Jacob, her younger son, and said unto him, Behold, thy brother Esau, as touching thee, doth comfort himself, purposing to kill thee. So Esau, in carrying out his purpose of revenge, planned to get satisfaction for himself; he thought he would feel better after having murdered his brother.
