The answer is: David

Ruth 4:17

Ruth's great-grandson, King David, carrying the legacy a few generations after Ruth and Boaz, is not just another name in a lineage; he’s a towering biblical figure whose story is rich with drama, music, and complexity. He started as a humble shepherd in Bethlehem—a picturesque town that would soon become even more significant in royal heritage.

To understand the sweep of history here, remember that Ruth was a Moabite. Her inclusion in the Israelite lineage speaks volumes about the breadth and inclusivity of God’s plan. It's remarkable that one of Israel’s greatest kings hailed from an ancestral line that included a foreign woman! This crossover is echoed later in the New Testament, particularly in Matthew's genealogy of Jesus, where Ruth’s story is reaffirmed in the lineage reaching the Messiah.

Speaking of lineage, let’s have some fun with trivia: David is historically famous not only for slaying Goliath but also for composing many of the Psalms—arguably some of the finest poetry known. And did you know that David was thought to be a master musician? When King Saul was tormented, it was David’s harp-playing that brought him comfort, highlighting the power of music in healing. Thus, from a fitting figure like David to the love story of Ruth, we witness both a earthly legacy and the universal themes of trust and redemption interwoven throughout the narrative—a gateway to deeper storytelling found in our holy texts.
