Thematic Bible: The right of redemption resigned by a man's giving one of his shoes to the next of kin

Now this was [the custom] in former time in Israel concerning redeeming and concerning exchanging, to confirm all things: a man took off his shoe, and gave it to his neighbor; and this was the [way of] attestation in Israel. So the near kinsman said to Boaz, "Buy it for yourself." He took off his shoe.
