Ruth 4:4-6

4And I thought I would apprise thee of it and say, Buy [it] in the presence of the inhabitants, and in the presence of the elders of my people. If thou wilt redeem [it], redeem; but if thou wilt not redeem, tell me, that I may know; for there is none to redeem besides thee; and I am after thee. And he said, I will redeem [it].

5And Boaz said, On the day thou buyest the field of the hand of Naomi, thou must buy [it] also of Ruth the Moabitess, the wife of the dead, to raise up the name of the dead upon his inheritance.

6And he that had the right of redemption said, I cannot redeem [it] for myself, lest I mar mine own inheritance. Redeem thou for thyself what I should redeem, for I cannot redeem [it].
