Genesis 38:16-18

16Then he turned to her by the way, and said, “Please let me come in to you”; for he did not know that she was his daughter-in-law. So she said, “What will you give me, that you may come in to me?”

17And he said, “I will send a young goat from the flock.” So she said, “Will you give me a pledge till you send it?”

18Then he said, “What pledge shall I give you?” So she said, “Your signet and cord, and your staff that is in your hand.” Then he gave them to her, and went in to her, and she conceived by him.
