Then Boaz said, “On the day you buy the land from Naomi and from Ruth the Moabitess, you acquire the dead man’s widow, in order to maintain the name of the dead with his property. At this, the kinsman-redeemer said, “Then I cannot redeem it because I might endanger my own estate. You redeem it yourself. I cannot do it.” (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 kinsman-redeemer said to Boaz, “Buy it yourself.” And he removed his sandal.
-Ruth 4:5-8
