Ruth 4:9-10

9At this, Boaz said to the elders and all the people, “You are witnesses today that I am buying from Naomi all that belonged to Elimelech, Chilion, and Mahlon. 10Moreover, I have acquired Ruth the Moabitess, Mahlon’s widow, as my wife, to raise up the name of the deceased through his inheritance, so that his name will not disappear from among his brothers or from the gate of his home. You are witnesses today.”
