Thematic Bible: By taking off the shoe

And the kinsman said, I cannot redeem it for myself, lest [by marrying a Moabitess] I endanger my own inheritance. Take my right of redemption yourself, for I cannot redeem it. Now formerly in Israel this was the custom concerning redeeming and exchanging. To confirm a transaction, a man pulled off his sandal and gave it to the other. This was the way of attesting in Israel. Therefore, when the kinsman said to Boaz, Buy it for yourself, he pulled off his sandal.
