Ruth 4:7-10

7(This is the way it used to be in Israel concerning buying back property and exchanging goods: In order to make every matter legal, a man would take off his sandal and give it to the other man. This was the way a contract was publicly approved in Israel.)

8So when the man said to Boaz, “Buy it for yourself,” he took off his sandal.

9Then Boaz said to the leaders and to all the people, “Today you are witnesses that I have bought from Naomi all that belonged to Elimelech and all that belonged to Chilion and Mahlon.

10In addition, I have bought as my wife the Moabite Ruth, Mahlon’s widow, to keep the inheritance in the dead man’s name. In this way the dead man’s name will not be cut off from his relatives or from the public records. Today you are witnesses.”
