Genesis 38:16-18

16He went over to her and said, “Come, let me sleep with you,” for he did not know that she was his daughter-in-law. She said, “What will you give me for sleeping with me?”

17“I will send you a young goat from my flock,” he replied. But she said, “Only if you leave something with me until you send it.”

18“What should I give you?” he asked. She answered, “Your signet ring, your cord, and the staff in your hand.” So he gave them to her and slept with her, and she became pregnant by him.
