Ruth 4:6-8 21st Century King James Version (KJ21)
6 And the kinsman said, “I cannot redeem it for myself, lest I mar mine own inheritance. Redeem thou my right for thyself, for I cannot redeem it.”
7 Now this was the manner in former times in Israel concerning redeeming and concerning exchanging, to confirm all things: a man plucked off his shoe, and gave it to his neighbor; and this was a testimony in Israel.
8 Therefore the kinsman said unto Boaz, “Buy it for thyself.” So he drew off his shoe.
