Genesis 38:16-18

16He turned aside to her along the road and said, “Come on! I want to have sex with you.” (He did not realize it was his daughter-in-law.) She asked, “What will you give me in exchange for having sex with you?”

17He replied, “I’ll send you a young goat from the flock.” She asked, “Will you give me a pledge until you send it?”

18He said, “What pledge should I give you?” She replied, “Your seal, your cord, and the staff that’s in your hand.” So he gave them to her and had sex with her. She became pregnant by him.
