Ruth 4:2-5

2Boaz chose ten of the town's leaders and he said to them, ‘Come and sit here.’ So they sat down.

3Then Boaz said to the family-redeemer, ‘Naomi has returned from Moab. She wants to sell the piece of land that belonged to our relative, Elimelech.

4I thought that I must tell you about this, in front of the leaders of our town. Tell us if you will buy this land from Naomi, so that all the people who sit here know what you decide. If you want to buy it, then you should buy it. If you do not want to buy it, then you must tell me. Then I will know what to do. You are the person who must decide. If you do not choose to buy the land, then I can buy it.’ The relative said, ‘I will buy it.’

5Then Boaz said, ‘You should also know this: When you buy the land from Naomi, you also have to marry the Moabite woman, Ruth. She is the widow of Elimelech's son. She will give birth to your children and Elimelech's land will continue to belong to his family.’
