Ruth 4: 13- 17
So Boaz took Ruth and she became his wife. When he made love to her, the Lord enabled her to conceive, and she gave birth to a son. The women said to Naomi: “Praise be to the Lord, who this day has not left you without a guardian-redeemer. May he become famous throughout Israel! He will renew your life and sustain you in your old age. For your daughter-in-law, who loves you and who is better to you than seven sons, has given him birth.”
Then Naomi took the child in her arms and cared for him. The women living there said, “Naomi has a son!” And they named him Obed. He was the father of Jesse, the father of David.
