The book of Ruth begins with the sad story of Naomi, whose husband died, and then both of her sons died. Naomi was left with her two daughters-in-law, Orpah and Ruth. Naomi set out from Moab to go back to Judah, and she told Orpah and Ruth to return to their homes. But Ruth insisted on staying with Naomi. She said, “Do not urge me to leave you or to return from following you. For where you go I will go, and where you lodge I will lodge. Your people shall be my people, and your God my God. Where you die I will die, and there will I be buried. May the Lord do so to me and more also if anything but death parts me from you” (Ruth 1:16-17).
Then, in God’s providential plan, Ruth meets Boaz, and Boaz redeems Ruth and marries her. And the book of Ruth ends with a genealogy—the genealogy of David. It begins with Perez (who, you remember, was the son of Judah and Tamar), and then it traces the lineage to Salmon (who was the father of Boaz by Rahab). Then Boaz fathered Obed by Ruth. And Obed fathered Jesse, and Jesse fathered David.
