Ruth 4:16-21 ESV
Then Naomi took the child and laid him on her lap and became his nurse. And the women of the neighborhood gave him a name, saying, “A son has been born to Naomi.” They named him Obed. He was the father of Jesse, the father of David.
Now these are the generations of Perez: Perez fathered Hezron, Hezron fathered Ram, Ram fathered Amminadab, Amminadab fathered Nahshon, Nahshon fathered Salmon, Salmon fathered Boaz, Boaz fathered Obed
