KJV
Now this [was the manner] in former time
in Israel concerning redeeming and concerning changing, for to confirm all
things; a man plucked off his shoe, and gave [it] to his neighbour: and this
[was] a testimony in Israel.
BSB
Now in former times in Israel, concerning the redemption or exchange of property, to make any matter legally binding a man would remove his sandal and give it to the other party, and this was a confirmation in Israel.
