About Tamar .
Tamar (Hebrew: תָּמָר, Modern tamar, Tiberian tāmār) is a person in 2 Samuel in the Hebrew Bible. She was the daughter of King David, and sister of Absalom. Her mother was Maacah, daughter of Talmai, king of Geshur. According to the narrative in 2 Samuel 13, she was raped by her half-brother Amnon.
Amnon rapes Tamar (2 Samuel 13:1-14)
According to the narrative, Amnon over time developed such strong feelings for his half-sister that he became ill over his lust for her. Amnon had a friend and counselor named Jonadab who, being said to be not only a "crafty man" but also Amnon's cousin, advised that Amnon pretend to be sick. Amnon did what was suggested , pretended to be sick and asked Tamar to prepare him food. He then asked her to have intercourse with him. When Tamar desperately tried to dissuade him, requesting him as a last argument to ask their father for her hand in marriage, Amnon raped her.
Immediate aftermath (2 Samuel 13:15-22)
After the rape, Amnon was overwhelmed by hatred for Tamar and he sent her home. Tamar expressed her grief by tearing her robe and marking her forehead with ashes. She went to her full brother Absalom, who attempted to comfort her and took her into his home where she remained a "desolate woman." When King David, Tamar's father, heard of her rape, he was angered but did nothing. According to the Dead Sea Scrolls and Greek version of 2 Samuel 13:21, "... he did not punish his son Amnon, because he loved him, for he was his firstborn."
Absalom murders Amnon (2 Samuel 13:23-29)
Absalom, who hated his half-brother Amnon for his rape of Tamar, waited for two years and then had Amnon murdered.
Assessment Mary J. Evans describes Tamar as a "beautiful, good-hearted obedient, righteous daughter who is totally destroyed by her family." After the rape, Amnon attempted to send Tamar away. She responded "No, my brother; for this wrong in sending me away is greater than the other that you did to me."(2 Samuel 13:15-16) This response references Deuteronomy 22:28 which states that a man who rapes a virgin must marry her. In Biblical law, it was unlawful for a man to have intercourse with his sister; Kyle McCarter suggests that either the laws are not in effect at this time or they will be overlooked by David, or they do not apply to the royal family. Michael D. Coogan, in his section on women in 2 Samuel, describes Tamar as a "passive figure" whose story is "narrated with considerable pathos." Coogan also points out the poignancy of the image at the end of the narrative story where Tamar is left as a "desolate woman in her brother Absalom's house."(2 Samuel 13:20) This ending verse about Tamar is meant to make the reader feel compassion and pity for her.
