Genesis 38:14

10The thing which he did was evil in the LORD’s sight, and he killed him also.

11Then Judah said to Tamar, his daughter-in-law, “Remain a widow in your father’s house, until Shelah, my son, is grown up;” for he said, “Lest he also die, like his brothers.” Tamar went and lived in her father’s house.

12After many days, Shua’s daughter, the wife of Judah, died. Judah was comforted, and went up to his sheep shearers to Timnah, he and his friend Hirah, the Adullamite.

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

14She took off the garments of her widowhood, and covered herself with her veil, and wrapped herself, and sat in the gate of Enaim, which is on the way to Timnah; for she saw that Shelah was grown up, and she wasn’t given to him as a wife.

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

16He turned to her by the way, and said, “Please come, let me come in to you,” for he didn’t know that she was his daughter-in-law. She said, “What will you give me, that you may come in to me?”

17He said, “I will send you a young goat from the flock.” She said, “Will you give me a pledge, until you send it?”

18He said, “What pledge will I give you?” She said, “Your signet and your cord, and your staff that is in your hand.” He gave them to her, and came in to her, and she conceived by him.
