Ruth 4:9 NIV
9 Then Boaz announced to the elders and all the people, “Today you are witnesses that I have bought from Naomi all the property of Elimelek, Kilion and Mahlon. 10 I have also acquired Ruth the Moabite, Mahlon’s widow, as my wife, in order to maintain the name of the dead with his property, so that his name will not disappear from among his family or from his hometown. Today you are witnesses!”
Boaz acquires the land of Elimelek,Kilion and Mahlon in the process also gets Ruth whilst Naomi is left outside.
If Boaz had wanted to continue the name of Mahlon why didn't he continue the name of Elimelek as well by taking Naomi too.
Why did Boaz not take Naomi as well?
