Ruth 4:7-9

New King James Version

^7 (A)Now this was the custom in former times in Israel concerning redeeming and exchanging, to confirm anything: one man took off his sandal and gave it to the other, and this was a confirmation in Israel.

⁸ Therefore the close relative said to Boaz, “Buy it for yourself.” So he took off his sandal. ⁹ And Boaz said to the elders and all the people, “You are witnesses this day that I have bought all that was Elimelech’s, and all that was Chilion’s and Mahlon’s, from the hand of Naomi.
