Ruth 4:7-10

(Now in earlier times in Israel, for the redemption and transfer of property to become final, one party took off his sandal and gave it to the other. This was the method of legalizing transactions in Israel.) So the guardian-redeemer said to Boaz, “Buy it yourself.” And he removed his sandal. Then Boaz announced to the elders and all the people, “Today you are witnesses that I have bought from Naomi all the property of Elimelek, Kilion and Mahlon. I have also acquired Ruth the Moabite, Mahlon’s widow, as my wife, in order to maintain the name of the dead with his property, so that his name will not disappear from among his family or from his hometown. Today you are witnesses!”
