Ruth echoes covenant language that Boaz had used with her in 2:12 about the Lord, in order to request that he fulfill his duty as her redeemer
Also reflects the action taken by the Lord in Ezekiel 16:8, when he takes Israel as his covenant bride
God covers our guilt and our sin, providing for and protecting us as his bride
Ruth’s request to Boaz is made in humility and faith, and points to how we approach the feet of the ultimate redeemer, Jesus Christ
Ruth does not presume or demand
Ruth again demonstrated herself to be good soil, bearing fruit in obedience
The redemption of Ruth by a kinsman redeemer preserves not only herself and Naomi, but the whole Davidic line, yielding the king of kings who redeems the church, Jesus Christ
