Genesis 38:17-20

17Judah replied, ‘I will take a young goat from my animals and I will give it to you.’ Tamar said, ‘Please give me something now to show me that you will really send the goat to me.’

18Judah asked her, ‘What should I give you?’ Tamar replied, ‘Give me your special ring and the string that holds it. And give me the stick that is in your hand.’ So Judah gave them to her. He had sex with her. As a result, she became pregnant.

19After this, Tamar left there and she took off her veil. She put her widow's clothes on again.

20Judah sent his friend Hirah, the Adullamite, to take a young goat back to where the woman had been. Judah wanted to get his special things back from the woman. But Hirah could not find the woman.
