2 Samuel 13:2-4

Modern English Version

² It depressed Amnon to the point of falling ill that Tamar his sister was a virgin, but it was impossible for Amnon to pursue her.

³ Now Amnon had a friend whose name was Jonadab the son of Shimeah, the brother of David, and Jonadab was a very crafty individual. ⁴ He asked him, “Why are you, the son of the king, so sullen morning after morning? Will you not tell me?”

Amnon told him, “I am in love with Tamar, the sister of Absalom my brother.”
