GENESIS 38:1  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.

GENESIS 38:2  And Judah saw there a daughter of a certain Canaanite, whose name was  Shuah; and he took her, and went in unto her.

GENESIS 38:3  And she conceived, and bare a son; and he called his name Er.

GENESIS 38:4  And she conceived again, and bare a son; and she called his name  Onan.

GENESIS 38:5  And she yet again conceived, and bare a son; and called his name  Shelah: and he was at Chezib, when she bare him.

GENESIS 38:6  And Judah took a wife for Er his firstborn, whose name was Tamar.

GENESIS 38:7  And Er, Judah's firstborn, was wicked in the sight of the LORD; and  the LORD slew him.

GENESIS 38:8  And Judah said unto Onan, Go in unto thy brother's wife, and marry  her, and raise up seed to thy brother.

GENESIS 38:9  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.

GENESIS 38:10  And the thing which he did displeased the LORD: wherefore he slew  him also.

GENESIS 38:11  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.

GENESIS 38:12  And in process 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.

GENESIS 38:13  And it was told Tamar, saying, Behold thy father in law goeth up to  Timnath to shear his sheep.

GENESIS 38:14  And she put her widow's garments off from her, and covered her with  a vail, and wrapped herself, and sat in an open place, which is by the way to  Timnath; for she saw that Shelah was grown, and she was not given unto him to  wife.

GENESIS 38:15  When Judah saw her, he thought her to be an harlot; because she had  covered her face.

GENESIS 38:16  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?

GENESIS 38:17  And he said, I will send thee a kid from the flock. And she said,  Wilt thou give me a pledge, till thou send it?

GENESIS 38:18  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.

GENESIS 38:19  And she arose, and went away, and laid by her vail from her, and put  on the garments of her widowhood.

GENESIS 38:20  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.

GENESIS 38:21  Then he asked the men of that place, saying, Where is the harlot,  that was openly by the way side? And they said, There was no harlot in this  place.

GENESIS 38:22  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.

GENESIS 38:23  And Judah said, Let her take it to her, lest we be shamed: behold, I  sent this kid, and thou hast not found her.

GENESIS 38:24  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.

GENESIS 38:25  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.

GENESIS 38:26  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.

GENESIS 38:27  And it came to pass in the time of her travail, that, behold, twins  were in her womb.

GENESIS 38:28  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.

GENESIS 38:29  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. (1)

GENESIS 38:30  And afterward came out his brother, that had the scarlet thread upon  his hand: and his name was called Zarah.
