Ruth 4:8

8 So when the next of kin said to Bo'az, "Buy it for yourself," he drew off his sandal.

Ruth 4:8 In-Context

6 Then the next of kin said, "I cannot redeem it for myself, lest I impair my own inheritance. Take my right of redemption yourself, for I cannot redeem it."
7 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.
8 So when the next of kin said to Bo'az, "Buy it for yourself," he drew off his sandal.
9 Then Bo'az said to the elders and all the people, "You are witnesses this day that I have bought from the hand of Na'omi all that belonged to Elim'elech and all that belonged to Chil'ion and to Mahlon.
10 Also Ruth the Moabitess, 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 brethren and from the gate of his native place; you are witnesses this day."
