Boaz offers the opportunity to the guardian redeemer to purchase the land of Naomi's relatives, which he declines, leading Boaz to step in and take responsibility by marrying Ruth. The birth of a son to Boaz and Ruth brings joy and renewal to Naomi.
In the final act of Ruth, the fullness of God's redemptive power, the renewal of all things, is unveiled through the marriage of Boaz and Ruth. From Act 4, with Bethany Allen.
