Genesis 38:1-30
1 And it came to pass at that time, that Judah went down from his brethren, and turned in to a certain Adullamite, whose name was Hirah.
2 And Judah saw there a daughter of a certain Canaanite, whose name was Shuah; and he took her, and went in unto her.
3 And she conceived, and bare a son; and he called his name Er.
4 And she conceived again, and bare a son; and she called his name Onan.
5 And she yet again conceived, and bare a son; and called his name Shelah: and he was at Chezib, when she bare him.
6 And Judah took a wife for Er his firstborn, whose name was Tamar.
7 And Er, Judah's firstborn, was wicked in the sight of the LORD; and the LORD slew him.
8 And Judah said unto Onan, Go in unto thy brother's wife, and marry her, and raise up seed to thy brother.
9 And Onan knew that the seed should not be his; and it came to pass, when he went in unto his brother's wife, that he spilled it on the ground, lest that he should give seed to his brother.
10 And the thing which he did displeaseda the LORD: wherefore he slew him also.
11 Then said Judah to Tamar his daughter in law, Remain a widow at thy father's house, till Shelah my son be grown: for he said, Lest peradventure he die also, as his brethren did. And Tamar went and dwelt in her father's house.
12 And in processb of time the daughter of Shuah Judah's wife died; and Judah was comforted, and went up unto his sheepshearers to Timnath, he and his friend Hirah the Adullamite.
13 And it was told Tamar, saying, Behold thy father in law goeth up to Timnath to shear his sheep.
14 And she put her widow's garments off from her, and covered her with a vail, and wrapped herself, and sat in an openc place, which is by the way to Timnath; for she saw that Shelah was grown, and she was not given unto him to wife.
15 When Judah saw her, he thought her to be an harlot; because she had covered her face.
16 And he turned unto her by the way, and said, Go to, I pray thee, let me come in unto thee; (for he knew not that she was his daughter in law.) And she said, What wilt thou give me, that thou mayest come in unto me?
17 And he said, I will send thee a kidd from the flock. And she said, Wilt thou give me a pledge, till thou send it?
18 And he said, What pledge shall I give thee? And she said, Thy signet, and thy bracelets, and thy staff that is in thine hand. And he gave it her, and came in unto her, and she conceived by him.
19 And she arose, and went away, and laid by her vail from her, and put on the garments of her widowhood.
20 And Judah sent the kid by the hand of his friend the Adullamite, to receive his pledge from the woman's hand: but he found her not.
21 Then he asked the men of that place, saying, Where is the harlot, that was openlye by the way side? And they said, There was no harlot in this place.
22 And he returned to Judah, and said, I cannot find her; and also the men of the place said, that there was no harlot in this place.
23 And Judah said, Let her take it to her, lest we be shamed:f behold, I sent this kid, and thou hast not found her.
24 And it came to pass about three months after, that it was told Judah, saying, Tamar thy daughter in law hath played the harlot; and also, behold, she is with child by whoredom. And Judah said, Bring her forth, and let her be burnt.
25 When she was brought forth, she sent to her father in law, saying, By the man, whose these are, am I with child: and she said, Discern, I pray thee, whose are these, the signet, and bracelets, and staff.
26 And Judah acknowledged them, and said, She hath been more righteous than I; because that I gave her not to Shelah my son. And he knew her again no more.
27 And it came to pass in the time of her travail, that, behold, twins were in her womb.
28 And it came to pass, when she travailed, that the one put out his hand: and the midwife took and bound upon his hand a scarlet thread, saying, This came out first.
29 And it came to pass, as he drew back his hand, that, behold, his brother came out: and she said, How hast thou broken forth? this breach be upon thee: therefore his name was called Pharez.
30 And afterward came out his brother, that had the scarlet thread upon his hand: and his name was called Zarah.
Judah's Adultery With Tamar
Perhaps out of disgust for his brothers' thoughts of killing Joseph and deceiving Jacob, Judah went to a city about twelve miles outside Bethlehem. He married a Canaanite woman who bore him three sons, Er, Onan and Shelah. Judah arranged a marriage contract for Er with a woman named Tamar. Before they could bear any children, God slew Er for wickedness. By the law of levirate marriage (see Deuteronomy 25:5-10), Onan was compelled to marry Tamar. The first son born to them would then be named for the deceased brother, Er, to keep his name alive. Onan apparently did not want to bear a child to carry on the memory of his brother, so he spilled his semen on the ground. God killed him for his act (Genesis 38:1-10).
Judah instructed Tamar to remain a widow in her father's house until Shelah reached an age for marriage. Actually, he feared for Shelah's life. Over the course of time, Judah's wife died. Tamar was told he was going up to Timnah to shear his sheep. She took off her widow's clothes, covered herself with a harlot's veil and waited by the road for Judah to pass. When he did, she made an agreement to have relations with him for a kid. He left his signet ring on a cord and shepherd's staff as collateral until he could send a kid back in payment.
When Tamar was found with child, Judah planned to burn her. However, she produced his signet ring on a cord and staff. Judah said she had been more righteous than he, however, both sinned in this matter. She bore twins, Perez and Zerah. It seems likely this story is included in the text because Judah was to receive the birthright. The Lord came out of the tribe of Judah. Also, Judah's sin is in stark contrast to Joseph's actions in the house of Potiphar (Genesis 38:1-30).
