Genesis 38:13-16

13And Tamar was told, “Behold, your father-in-law is going up to 1Timnah to shear his sheep.”

14So she 2removed her widow’s garments and 3covered herself with a 4veil, and wrapped herself, and sat in the gateway of 5Enaim, which is on the road to Timnah; for she saw that Shelah had grown up, and 6she had not been given to him as a wife.

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

16So he turned aside to her by the road, and said, “7Here now, let me have relations 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 have relations with me?”
