Now this was the custom in former times in Israel concerning redeeming and exchanging: to confirm a transaction, the one drew off his sandal and gave it to the other, and this was the manner of attesting in Israel. So when the redeemer said to Boaz, “Buy it for yourself,” he drew off his sandal. Then Boaz said to the elders and all the people, “You are witnesses this day that I have bought from the hand of Naomi all that belonged to Elimelech and all that belonged to Chilion and to Mahlon. Also Ruth the Moabite, the widow of Mahlon, I have bought to be my wife, to perpetuate the name of the dead in his inheritance, that the name of the dead may not be cut off from among his brothers and from the gate of his native place. You are witnesses this day.” Then all the people who were at the gate and the elders said, “We are witnesses. May the LORD make the woman, who is coming into your house, like Rachel and Leah, who together built up the house of Israel. May you act worthily in Ephrathah and be renowned in Bethlehem, and may your house be like the house of Perez, whom Tamar bore to Judah, because of the offspring that the LORD will give you by this young woman.”
Ruth 4:7-12
