Genesis 38:13-17 New King James Version (NKJV)

13. And it was told Tamar, saying, “Look, your father-in-law is going up to Timnah to shear his sheep.”

14. So she took off her widow’s garments, covered herself with a veil and wrapped herself, and sat in an open place which was on the way to Timnah; for she saw that Shelah was grown, and she was not given to him as a wife.

15. When Judah saw her, he thought she was a harlot, because she had covered her face.

16. Then 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?”

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