Ruth 4:8

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.

10 And, further, I have taken Ruth, the Moabitess, who was the wife of Mahlon, to be my wife, to keep the name of the dead man living in his heritage, so that his name may not be cut off from among his countrymen, and from the memory of his town: you are witnesses this day.

11 And all the people who were in the public place, and the responsible men, said, We are witnesses. May the Lord make this woman, who is about to come into your house, like Rachel and Leah, which two were the builders of the house of Israel: and may you have wealth in Ephrathah, and be great in Beth-lehem;
