Numbers 26:20

And the sons of Judah; Er, and Onan, and Shelah, and Pharez, and Zerah: but Er and Onan died in the land of Canaan. And the sons of Pharez were Hezron and Hamul.

And Pethahiah the son of Meshezabeel, of the children of Zerah the son of Judah, was at the king’s hand in all matters concerning the people.

The sons of Judah; Er, and Onan, and Shelah: which three were born unto him of the daughter of Shua the Canaanitess. And Er, the firstborn of Judah, was evil in the sight of the Lord; and he slew him. And Tamar his daughter in law bare him Pharez and Zerah. All the sons of Judah were five. The sons of Pharez; Hezron, and Hamul. And the sons of Zerah; Zimri, and Ethan, and Heman, and Calcol, and Dara: five of them in all. And the sons of Carmi; Achar, the troubler of Israel, who transgressed in the thing accursed. And the sons of Ethan; Azariah.

The sons of Shelah the son of Judah were, Er the father of Lecah, and Laadah the father of Mareshah, and the families of the house of them that wrought fine linen, of the house of Ashbea,

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.

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.

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. And it came to pass in the time of her travail, that, behold, twins were in her womb. 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. 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. And afterward came out his brother, that had the scarlet thread upon his hand: and his name was called Zarah.

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

Which was the son of Aminadab, which was the son of Aram, which was the son of Esrom, which was the son of Phares, which was the son of Juda,

And Judas begat Phares and Zara of Thamar; and Phares begat Esrom; and Esrom begat Aram;

And at Jerusalem dwelt certain of the children of Judah, and of the children of Benjamin. Of the children of Judah; Athaiah the son of Uzziah, the son of Zechariah, the son of Amariah, the son of Shephatiah, the son of Mahalaleel, of the children of Perez;

All the sons of Perez that dwelt at Jerusalem were four hundred threescore and eight valiant men.

Now these are the generations of Pharez: Pharez begat Hezron, And Hezron begat Ram, and Ram begat Amminadab, And Amminadab begat Nahshon, and Nahshon begat Salmon, And Salmon begat Boaz, and Boaz begat Obed, And Obed begat Jesse, and Jesse begat David.
