6 Then the relative said, "Oh, I can't do that - I'd jeopardize my own family's inheritance. You go ahead and buy it - you can have my rights - I can't do it." 7 In the olden times in Israel, this is how they handled official business regarding matters of property and inheritance: a man would take off his shoe and give it to the other person. This was the same as an official seal or personal signature in Israel. 8 So when Boaz's "redeemer" relative said, "Go ahead and buy it," he signed the deal by pulling off his shoe.

Commentary on Ruth 4:1-8
(Read Ruth 4:1-8)
This matter depended on the laws given by Moses about inheritances, and doubtless the whole was settled in the regular and legal manner. This kinsman, when he heard the conditions of the bargain, refused it. In like manner many are shy of the great redemption; they are not willing to espouse religion; they have heard well of it, and have nothing to say against it; they will give it their good word, but they are willing to part with it, and cannot be bound to it, for fear of marring their own inheritance in this world. The right was resigned to Boaz. Fair and open dealing in all matters of contract and trade, is what all must make conscience of, who would approve themselves true Israelites, without guile. Honesty will be found the best policy.
