So time passed and Judah was making no effort to arrange another levirate marriage between Shelah and Tamar who desired children and not wanting to make a career of widowhood. She was still a young woman. Judahâ€™s wife died and he went through a period of ritual mourning as the text says that and Judah was comforted. Later he and his friend Hirah went up to the sheep-shearers. This was a festive time for them and Judah now done with mourning was going to join in the party atmosphere. Tamar became aware of Judahâ€™s travel to the party with the sheep shearers with Hirah and she devised a plan to force him into a role of a levir for her. In her contrivance she planned to entrap him. She changed out of her widowâ€™s clothes and made herself appear as an adherent of Astarte, which was a sacred prostitute. She then put on a veil, which had several connotations of that day. Brides principally wore them on their wedding night and so did prostitutes wanting to appear as a wholesome bride. So a veiled woman in public gave off the message that she was a prostitute available for sexual intercourse. She had essentially dressed herself as a cult prostitute and waited for Judah to appear at the city gate of Enaim. Her actions while retaliatory for not getting Shelah put her into a doubly sinful situation. She was legally betrothed to Shelah regardless of what Judah was preventing and she was planning on an incestuous relationship with Judah.
