Ruth 4:17 (KJV)

And let thy house be like the house of Pharez, whom Tamar bare unto Judah, of the seed which the LORD shall give thee of this young woman.

So Boaz took Ruth, and she was his wife: and when he went in unto her, the LORD gave her conception, and she bare a son.

And the women said unto Naomi, Blessed be the LORD, which hath not left thee this day without a kinsman, that his name may be famous in Israel.

And he shall be unto thee a restorer of thy life, and a nourisher of thine old age: for thy daughter in law, which loveth thee, which is better to thee than seven sons, hath born him.

And Naomi took the child, and laid it in her bosom, and became nurse unto it.

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.
