Ruth 4:7-10

7At an earlier period in Israel, a man removed his sandal and gave it to the other party in order to make any matter legally binding concerning the right of redemption or the exchange of property. This was the method of legally binding a transaction in Israel.

8So the redeemer removed his sandal and said to Boaz, “Buy back the property yourself.”

9Boaz said to the elders and all the people, “You are witnesses today that I am buying from Naomi everything that belonged to Elimelech, Chilion, and Mahlon.

10I have also acquired Ruth the Moabitess, Mahlon’s widow, as my wife, to perpetuate the deceased man’s name on his property, so that his name will not disappear among his relatives or from the gate of his hometown. You are witnesses today.”
