Ruth 4:6-8

4:6 The guardian said, “Then I am unable to redeem it, for I would ruin my own inheritance in that case. You may exercise my redemption option, for I am unable to redeem it.” 4:7 (Now this used to be the customary way to finalize a transaction involving redemption in Israel: A man would remove his sandal and give it to the other party. This was a legally binding act in Israel.) 4:8 So the guardian said to Boaz, “You may acquire it,” and he removed his sandal.
