2 Samuel 13:1, 14, 28-29

David had a son named Absalom and a son named Amnon. Absalom had a beautiful sister named Tamar, and Amnon loved her.

But Amnon refused to listen to her. He was stronger than she was, so he forced her to have sexual relations with him.

Then Absalom instructed his servants, “Watch Amnon. When he is drunk, I will tell you, ‘Kill Amnon.’ Right then, kill him! Don’t be afraid, because I have commanded you! Be strong and brave!” So Absalom’s young men killed Amnon as Absalom commanded, but all of David’s other sons got on their mules and escaped.
