Ruth 4:11-13 (NRSV)
11 Then all the people who were at the gate, along with the elders, said, “We are witnesses. May the Lord make the woman who is coming into your house like Rachel and Leah, who together built up the house of Israel. May you produce children in Ephrathah and bestow a name in Bethlehem; 12 and, through the children that the Lord will give you by this young woman, may your house be like the house of Perez, whom Tamar bore to Judah.” 13 So Boaz took Ruth and she became his wife. When they came together, the Lord made her conceive, and she bore a son.
