Genesis 38:15-18

15When Judah saw her, he thought she was a prostitute, for she had covered her face.

16Not realizing that she was his daughter-in-law, he went over to her by the roadside and said, “Come now, let me sleep with you.” “And what will you give me to sleep with you?” she asked.

17“I’ll send you a young goat from my flock,” he said. “Will you give me something as a pledge until you send it?” she asked.

18He said, “What pledge should I give you?” “Your seal and its cord, and the staff in your hand,” she answered. So he gave them to her and slept with her, and she became pregnant by him.
