Ruth 4:5-8

5Boaz continued, “When you buy the field from Naomi, you will also assume responsibility for the Moabite Ruth, the dead man’s widow. This keeps the inheritance in the dead man’s name.”

6The man replied, “In that case I cannot assume responsibility for her. If I did, I would ruin my inheritance. Take all my rights to buy back the property for yourself, because I cannot assume that responsibility.”

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.
