3 Boaz then said to his relative, "The piece of property that belonged to our relative Elimelech is being sold by his widow Naomi, who has just returned from the country of Moab. 4 I thought you ought to know about it. Buy it back if you want it - you can make it official in the presence of those sitting here and before the town elders. You have first redeemer rights. If you don't want it, tell me so I'll know where I stand. You're first in line to do this and I'm next after you." He said, "I'll buy it." 5 Then Boaz added, "You realize, don't you, that when you buy the field from Naomi, you also get Ruth the Moabite, the widow of our dead relative, along with the redeemer responsibility to have children with her to carry on the family inheritance."

(Read Ruth 4:1-8)
This matter depended on the laws given by Moses about inheritances, and doubtless the whole was settled in the regular and legal manner. This kinsman, when he heard the conditions of the bargain, refused it. In like manner many are shy of the great redemption; they are not willing to espouse religion; they have heard well of it, and have nothing to say against it; they will give it their good word, but they are willing to part with it, and cannot be bound to it, for fear of marring their own inheritance in this world. The right was resigned to Boaz. Fair and open dealing in all matters of contract and trade, is what all must make conscience of, who would approve themselves true Israelites, without guile. Honesty will be found the best policy.
