Ruth 4:7-10

(At that time in Israel, in order to finalize a transaction concerning redeeming and transferring property, a man would customarily remove a sandal and give it to the other party, making the contract legally binding.) So when the kinsman-redeemer said to Boaz, “Take my purchase option of redemption for yourself,” he took off his sandal and gave it to Boaz. Then Boaz turned to the elders and announced publicly, “Today, you are witnesses that I have purchased from the hand of Naomi all that belonged to Elimelech and all that belonged to Chilion and Mahlon. I have also acquired Ruth the Moabite, Mahlon’s widow, to be my wife. I will raise children with her who will maintain the dead man’s name on his inheritance so that the name of the dead may not be cut off from his village and from his family line. Today, you are witnesses of this transaction.”
