Genesis 27:41-42

Brenton(i) 41 And Esau was angry with Jacob because of the blessing, with which his father blessed him; and Esau said in his mind, Let the days of my father's mourning draw nigh, that I may slay my brother Jacob. 42 And the words of Esau her elder son were reported to Rebecca, and she sent and called Jacob her younger son, and said to him, Behold, Esau thy brother threatens thee to kill thee.
