Genesis 34:5-7

34:5 When Jacob heard that Shechem had violated his daughter Dinah, his sons were with the livestock in the field. So Jacob remained silent until they came in.

34:6 Then Shechem’s father Hamor went to speak with Jacob about Dinah. 34:7 Now Jacob’s sons had come in from the field when they heard the news. They were offended and very angry because Shechem had disgraced Israel by sexually assaulting Jacob’s daughter, a crime that should not be committed.
