The story of Ruth and Boaz illustrates the biblical concept of redemption.

Here's a step-by-step explanation:

1. The Book of Ruth is a part of the Bible's Old Testament. It tells the story of Ruth, a Moabite woman, who after being widowed, remains with her mother-in-law, Naomi.

2. Naomi decides to return to Bethlehem, her homeland, and Ruth insists on going with her, saying "Where you go I will go, and where you stay I will stay. Your people will be my people and your God my God."

3. Once in Bethlehem, Ruth goes to gather leftover grain in the fields of Boaz, a relative of Naomi's deceased husband. Boaz shows kindness to Ruth, protects her and eventually marries her.

4. The concept of redemption is illustrated in this story through Boaz's actions. In the Bible, redemption often refers to the act of buying something back or freeing someone from bondage through a payment. In this case, Boaz redeems Ruth and Naomi from their plight as widows (and in Ruth's case, a foreigner) by marrying Ruth and providing for them. This act of redemption is also a foreshadowing of the ultimate redemption story in the Bible - Jesus Christ redeeming mankind through his death and resurrection.
