Ruth 4:16

So Boaz took Ruth and she became his wife; and he went in to her, and the LORD enabled her to conceive, and she bore a son.

The women said to Naomi, “Blessed be the LORD, who has not left you today without a near kinsman. Let his name be famous in Israel.

He shall be to you a restorer of life and sustain you in your old age; for your daughter-in-law, who loves you, who is better to you than seven sons, has given birth to him.”

The women, her neighbors, gave him a name, saying, “A son is born to Naomi”. They named him Obed. He is the father of Jesse, the father of David.

Now this is the history of the generations of Perez: Perez became the father of Hezron,

and Hezron became the father of Ram, and Ram became the father of Amminadab,
