Genesis 38:16-18

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

17He answered, “I will send you a young goat from the flock.” And she said, “Will you give me a pledge [as a deposit] until you send it?”

18He said, “What pledge shall I give you?” She said, “Your seal and your cord, and the staff that is in your hand.” So he gave them to her and was intimate with her, and she conceived by him.
