Ruth 4:6

3 Then he said to the near relation, Naomi, who has come back from the country of Moab, is offering for a price that bit of land which was our brother Elimelech's:

4 And it was in my mind to give you the chance of taking it, with the approval of those seated here and of the responsible men of my people. If you are ready to do what it is right for a relation to do, then do it: but if you will not do it, say so to me now; for there is no one who has the right to do it but you, and after you myself. And he said, I will do it.

5 Then Boaz said, On the day when you take this field, you will have to take with it Ruth, the Moabitess, the wife of the dead, so that you may keep the name of the dead living in his heritage.

6 And the near relation said, I am not able to do the relation's part, for fear of damaging the heritage I have: you may do it in my place, for I am not able to do it myself.

7 Now, in earlier times this was the way in Israel when property was taken over by a near relation, or when there was a change of owner. To make the exchange certain one man took off his shoe and gave it to the other; and this was a witness in Israel.

8 So the near relation said to Boaz, Take it for yourself. And he took off his shoe.

9 Then Boaz said to the responsible men and to all the people, You are witnesses today that I have taken at a price from Naomi all the property which was Elimelech's, and everything which was Chilion's and Mahlon's.
