In this chapter we see Boaz initiating and securing Naomi & Ruth’s redemption, at great cost to himself. We also see Naomi’s restoration, who went from full to empty, back to full again. These, though, are just dim shadows in comparison to the redemption and restoration we find in Jesus. Finally, we see the resulting family tree of King David, who himself points ahead to King Jesus. In Matthew chapter 1, we see Jesus’ family tree, which includes outsiders and moral failures, reminding us that Jesus is a friend of sinners who turn to him in trust.
