The daughter of David and Maachah, a Geshurite princess, and thus sister of Absalom. She was raped by her half-brother Amnon, who afterwards had his servants throw her out. "Then Tamar put ashes on her head, and tore her robe of many colors that was on her, and laid her hand on her head and went away crying bitterly." Absalom took her into his house and counseled her to keep quiet. When David found out, he became very angry but did nothing (possibly because Amnon was his first-born son).
Absalom hated his half-brother for what he had done, and two years later, at the time of the festivities connected with a great sheep-shearing at Baal-hazor, had his servants murder Amnon.
It is also the name of a daughter of Absalom.1
