Ruth 4:6

3 And he said to the kinsman-redeemer, “Naomi, who has returned from the land of Moab, is selling the piece of land that belonged to our brother Elimelech.

4 I thought I should inform you that you may buy it back in the presence of those seated here and in the presence of the elders of my people. If you want to redeem it, do so. But if you will not redeem it, tell me so I may know, because there is no one but you to redeem it, and I am next after you.” “I will redeem it,” he replied.

5 Then Boaz said, “On the day you buy the land from Naomi and also from Ruth the Moabitess, you must also acquire the widow of the deceased in order to raise up the name of the deceased on his inheritance.”

6 The kinsman-redeemer replied, “I cannot redeem it myself, or I would jeopardize my own inheritance. Take my right of redemption, because I cannot redeem it.”

7 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.

8 So the kinsman-redeemer removed his sandal and said to Boaz, “Buy it for yourself.”

9 At this, Boaz said to the elders and all the people, “You are witnesses today that I am buying from Naomi all that belonged to Elimelech, Chilion, and Mahlon.
