Ruth 4:9-10

9Then Boaz said to the elders and to the crowd standing around, “You are witnesses that today I have bought from Naomi all the property of Elimelech, Kilion, and Mahlon.

10And with the land I have acquired Ruth, the Moabite widow of Mahlon, to be my wife. This way she can have a son to carry on the family name of her dead husband and to inherit the family property here in his hometown. You are all witnesses today.”
