Ruth 4:7-10

Now this was the custom in former time in Israel concerning redeeming and concerning exchanging, to confirm all things: a man drew off his shoe, and gave it to his neighbor; and this was the manner of attestation in Israel. So the near kinsman said unto Boaz, Buy it for thyself. And he drew off his shoe. And Boaz said unto the elders, and unto all the people, Ye are witnesses this day, that I have bought all that was Elimelech’s, and all that was Chilion’s and Mahlon’s, of the hand of Naomi. Moreover Ruth the Moabitess, the wife of Mahlon, have I purchased to be my wife, to raise up the name of the dead upon his inheritance, that the name of the dead be not cut off from among his brethren, and from the gate of his place: ye are witnesses this day.
