What does Ruth 4:10 mean?
After legally purchasing Naomi's husband's land and taking responsibility for Naomi (Ruth 4:9), Boaz goes a step further. To buy the land was his responsibility as a kinsman-redeemer (Leviticus 25:25–28, 47–49). To marry Ruth as Naomi's surrogate to provide an heir who will re-inherit the land is not his responsibility. He is not Elimelech's brother (Deuteronomy 25:5–6).Land and a continuous family line were two of the most important parts of Israelite culture. Much of the book of Joshua is a record of dividing the land of Canaan among the tribes, clans, and families of the Israelites. One of the most severe consequences for a family that rebelled against God was to have their name erased (Deuteronomy 29:20). For the nation, judgment included famine, pestilence, or defeat in war—curses on the land (Deuteronomy 28:20–44). God punished the Israelites when they sinned, but He also restored them when they repented (Leviticus 26:40–45). Elimelech sold his land and neither he nor his sons lived to redeem it. But because of the "repentance" of Ruth—that she "turned away" from her land and her gods and toward Israel and Yahweh (Ruth 1:16–17)—their land and their family name will be restored.
The story of Ruth is about lovingkindness and loyalty. Ruth showed both when she forsook her people and religion, accompanied Naomi to Bethlehem, and did everything in her power to win her a life, a home, and an heir. Ruth was responding to the lovingkindness and loyalty Naomi had shown her during their lives together in Moab. Boaz responded to the mutual display by using his power as male landowner of honor to fulfill Ruth's plan.
Behind it all, however, is God's lovingkindness and loyalty. When Naomi arrived in Bethlehem, she thought God had abandoned her and forsaken His promise to care for her as an Israelite (Ruth 1:19–21). She sees now that God was working all along to restore to her what she had lost.
