Genesis 38
16 Ref And turning to her by the roadside, he said to her, Let me come in to you; for he had no idea that she was his daughter-in-law. And she said, What will you give me as my price?
17 Ref And he said, I will give you a young goat from the flock. And she said, What will you give me as a sign till you send it?
18 Ref And he said, What would you have? And she said, Your ring and its cord and the stick in your hand. So he gave them to her and went in to her, and she became with child by him.
