A character from the Hebrew Bible/ Old Testament. Tamar married Er the oldest of the sons of Judah, but Er was wicked in the sight of the Lord and so he was killed. Then Tamar married Onan the second son of Judah who God also struck down. After the death of her second husband she went to remain a widow in the house of her father untill Judah's youngest son Sheleh grew up. But when he had, Judah did not give Tamar to him. Instead Tamar ended up sleeping with her father-in-law (though he did not know who she was) and getting with child. When Judah heard she was pregnant he went to have her burnt, but she proved to him that he was the father and so he spared her. She bore him twins Pharez and Zarah.
