Ruth 4:7-10

7Now this was the manner in former time in Israel concerning redeeming and concerning changing, for confirming all things; a man took off his shoe, and gave it to his neighbour: and this was a testimony in Israel. 8Therefore the kinsman said to Boaz, Buy it for thyself. So he drew off his shoe.

9And Boaz said to the elders, and to 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. 10Moreover 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.
