Ruth 4:5-7

Complete Jewish Bible

⁵ Then Bo‘az said, “The same day you buy the field from Na‘omi, you must also buy Rut the woman from Mo’av, the wife of the deceased [son], in order to raise up in the name of the deceased an heir for his property.” ⁶ The redeemer said, “Then I can’t redeem it for myself, because I might put my own inheritance at risk. You, take my right of redemption on yourself; because I can’t redeem it.”

⁷ In the past, this is what was done in Isra’el to validate all transactions involving redemption and exchange: a man took off his shoe and gave it to the other party; this was the form of attestation in Isra’el.
