"No, no!" Tamar cried. "To reject me now is a greater wrong than what you have already done to me." But Amnon wouldn't listen to her.
He shouted for his servant and demanded, "Throw this woman out, and lock the door behind her!"
So the servant put her out. She was wearing a long, beautiful robe, as was the custom in those days for the king's virgin daughters.
References for 2 Samuel 13:18
But now Tamar tore her robe and put ashes on her head. And then, with her face in her hands, she went away crying.
Her brother Absalom saw her and asked, "Is it true that Amnon has been with you? Well, don't be so upset. Since he's your brother anyway, don't worry about it." So Tamar lived as a desolate woman in Absalom's house.
When King David heard what had happened, he was very angry.
And though Absalom never spoke to Amnon about it, he hated Amnon deeply because of what he had done to his sister.
Two years later, when Absalom's sheep were being sheared at Baal-hazor near Ephraim, Absalom invited all the king's sons to come to a feast.
He went to the king and said, "My sheep-shearers are now at work. Would the king and his servants please come to celebrate the occasion with me?"
The king replied, "No, my son. If we all came, we would be too much of a burden on you." Absalom pressed him, but the king wouldn't come, though he sent his thanks.
"Well, then," Absalom said, "if you can't come, how about sending my brother Amnon instead?" "Why Amnon?" the king asked.
