Ruth 4:7

And this was formerly a custom in Israel, on occasion of surrendering rights of kinship, or of selling and buying land, in order to confirm any matter; a man drew off his shoe and gave it to the other contracting party. This was attestation in Israel. We give a free translation. The custom was significant enough. He who sold land, or surrendered his right to act as a kinsman in buying land, intimated by the symbolical act of taking off his shoe, and handing it to his friend, that he freely gave up his right to walk upon the soil, in favor of the person who had acquired the possession. Corresponding symbolical acts, in connection with the transfer of lands, have been common, and probably still are, in many countries. No doubt the shoe, after being received, would be immediately returned.
