2 Samuel 13:20-24

Then Absalom her brother said to her, “Has Amnon your brother been with you? But now keep silent, my sister, he is your brother; do not take this matter to heart.” So Tamar remained and was isolated in her brother Absalom’s house.

Now when King David heard about all these matters, he became very angry.

But Absalom did not speak with Amnon either good or bad; for Absalom hated Amnon because he had violated his sister Tamar.

Now it came about after two full years that Absalom had sheepshearers in Baal-hazor, which is near Ephraim, and Absalom invited all the king’s sons to celebrate. Absalom Avenges Tamar

And Absalom came to the king and said, “Behold now, your servant has sheepshearers; may the king and his servants please go with your servant.”
