Ruth 4:7 WEB

⁵  Then said Boaz, What day you buy the field of the hand of Naomi, you must buy it also of Ruth the Moabitess, the wife of the dead, to raise up the name of the dead on his inheritance.

⁶  The near kinsman said, I can't redeem it for myself, lest I mar my own inheritance: take my right of redemption on you; for I can't redeem it.

⁷  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.

⁸  So the near kinsman said to Boaz, Buy it for yourself. He drew off his shoe.

⁹  Boaz said to the elders, and to 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, of the hand of Naomi.
