Ruth 4:7–8

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.

(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.

At an earlier period in Israel, a man removed his sandal and gave it to the other party in order to make any matter legally binding concerning the right of redemption or the exchange of property. This was the method of legally binding a transaction in Israel.

So the redeemer removed his sandal and said to Boaz, “Buy back the property yourself.”

Now in those days it was the custom in Israel for anyone transferring a right of purchase to remove his sandal and hand it to the other party. This publicly validated the transaction. So the other family redeemer drew off his sandal as he said to Boaz, “You buy the land.”

(Now this was the custom in former times in Israel concerning the kinsman-redemption and transfer of property: to confirm the matter, a man removed his sandal and gave it to his fellow countryman. This was the manner of attesting in Israel.) So the redeemer said to Boaz, “Acquire it for yourself,” and he removed his sandal.

Now this was the manner in former time in Israel concerning redeeming and concerning changing, for to confirm all things; a man plucked off his shoe, and gave it to his neighbour: and this was a testimony in Israel. Therefore the kinsman said unto Boaz, Buy it for thee. So he drew off his shoe.
