I hope your week has been a good on. We've read how Ruth has been gleaning in Boaz's field to keep her and Naomi alive. Now Naomi looks for a way to give Ruth some longer term security, which in this case means a husband. Her unconventional match-making makes for a good read. When you read threshing floor, think fishing trip: some time when men get together to work and celebrate. The next-of-kin stuff is hard for us to understand, but the short version is that in biblical Israel the next of kin had the obligation to buy the land for family in need so the land stayed in the family. In a case like Ruth's where she is a widow without children, her husband's next of kin also has the obligation to marry her so she can be provided for and to provide an heir for her dead husband. That way his family line and land are preserved and the widow would be cared for.
Blessings on your weekend,
