2 Samuel 13:8-12

So Tamar went to her brother Amnon’s house, and he was lying in bed. And she took dough, kneaded it, made pastries in his sight, and baked the pastries.

Then she took the tray and served them to him, but he refused to eat. And Amnon said, “Have everyone leave me.” So everyone left him.

Then Amnon said to Tamar, “Bring the food into the bedroom, so that I may eat from your hand.” So Tamar took the pastries which she had made and brought them into the bedroom to her brother Amnon.

When she brought them to him to eat, he took hold of her and said to her, “Come, sleep with me, my sister.”

But she said to him, “No, my brother, do not violate me, for such a thing is not done in Israel; do not do this disgraceful sin!
