Genesis 38:6-19

Judah got a wife for Er, his firstborn. Her name was Tamar. But Judah’s firstborn, Er, grievously offended GOD and GOD took his life. So Judah told Onan, “Go and sleep with your brother’s widow; it’s the duty of a brother-in-law to keep your brother’s line alive.” But Onan knew that the child wouldn’t be his, so whenever he slept with his brother’s widow he spilled his semen on the ground so he wouldn’t produce a child for his brother. GOD was much offended by what he did and also took his life. So Judah stepped in and told his daughter-in-law Tamar, “Live as a widow at home with your father until my son Shelah grows up.” He was worried that Shelah would also end up dead, just like his brothers. So Tamar went to live with her father. Time passed. Judah’s wife, Shua’s daughter, died. When the time of mourning was over, Judah with his friend Hirah of Adullam went to Timnah for the sheep shearing. Tamar was told, “Your father-in-law has gone to Timnah to shear his sheep.” She took off her widow’s clothes, put on a veil to disguise herself, and sat at the entrance to Enaim which is on the road to Timnah. She realized by now that even though Shelah was grown up, she wasn’t going to be married to him. Judah saw her and assumed she was a prostitute since she had veiled her face. He left the road and went over to her. He said, “Let me sleep with you.” He had no idea that she was his daughter-in-law. She said, “What will you pay me?” “I’ll send you,” he said, “a kid goat from the flock.” She said, “Not unless you give me a pledge until you send it.” “So what would you want in the way of a pledge?” She said, “Your personal seal-and-cord and the staff you carry.” He handed them over to her and slept with her. And she got pregnant. She then left and went home. She removed her veil and put her widow’s clothes back on.
