Ruth 4:13-17

So Boaz took Ruth, and she became his wife, and he had relations with her. And the Lord enabled her to conceive, and she gave birth to a son.

Then the women said to Naomi, “Blessed is the Lord who has not left you without a redeemer today, and may his name become famous in Israel.

May he also be to you one who restores life and sustains your old age; for your daughter-in-law, who loves you and is better to you than seven sons, has given birth to him.” The Line of David

Then Naomi took the child and laid him in her lap, and became his nurse.

And the neighbor women gave him a name, saying, “A son has been born to Naomi!” So they named him Obed. He is the father of Jesse, the father of David.
