2 Samuel 13:1-2

Darby Translation

13 And it came to pass after this, that Absalom the son of David having a beautiful sister, whose name was Tamar, Amnon the son of David loved her.

² And Amnon was so vexed, that he fell sick for his sister Tamar; for she was a virgin; and it seemed difficult for Amnon to do the least thing to her.
