Ruth 4:13-15

So Boaz took Ruth home as his wife and had sexual relations with her. The LORD let her become pregnant, and she gave birth to a son. The women told Naomi, “Praise the LORD who gave you this grandson. May he become famous in Israel. He will give you new life and will take care of you in your old age because of your daughter-in-law who loves you. She is better for you than seven sons, because she has given birth to your grandson.”
