Genesis 38:13-30

38:13 Tamar was told, “Look, your father-in-law is going up to Timnah to shear his sheep.” 38:14 So she removed her widow’s clothes and covered herself with a veil. She wrapped herself and sat at the entrance to Enaim which is on the way to Timnah. (She did this because she saw that she had not been given to Shelah as a wife, even though he had now grown up.)

38:15 When Judah saw her, he thought she was a prostitute because she had covered her face. 38:16 He 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?” 38:17 He replied, “I’ll send you a young goat from the flock.” She asked, “Will you give me a pledge until you send it?” 38:18 He 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. 38:19 She left immediately, removed her veil, and put on her widow’s clothes.

38:20 Then Judah had his friend Hirah the Adullamite take a young goat to get back from the woman the items he had given in pledge, but Hirah could not find her. 38:21 He asked the men who were there, “Where is the cult prostitute who was at Enaim by the road?” But they replied, “There has been no cult prostitute here.” 38:22 So he returned to Judah and said, “I couldn’t find her. Moreover, the men of the place said, ‘There has been no cult prostitute here.’” 38:23 Judah said, “Let her keep the things for herself. Otherwise we will appear to be dishonest. I did indeed send this young goat, but you couldn’t find her.”

38:24 After three months Judah was told, “Your daughter-in-law Tamar has turned to prostitution, and as a result she has become pregnant.” Judah said, “Bring her out and let her be burned!” 38:25 While they were bringing her out, she sent word to her father-in-law: “I am pregnant by the man to whom these belong.” Then she said, “Identify the one to whom the seal, cord, and staff belong.” 38:26 Judah recognized them and said, “She is more upright than I am, because I wouldn’t give her to Shelah my son.” He did not have sexual relations with her again.

38:27 When it was time for her to give birth, there were twins in her womb. 38:28 While she was giving birth, one child put out his hand, and the midwife took a scarlet thread and tied it on his hand, saying, “This one came out first.” 38:29 But then he drew back his hand, and his brother came out before him. She said, “How you have broken out of the womb!” So he was named Perez. 38:30 Afterward his brother came out – the one who had the scarlet thread on his hand – and he was named Zerah.

4:12 May your family become like the family of Perez – whom Tamar bore to Judah – through the descendants the Lord gives you by this young woman.”
