What Is the Significance of Ruth in Israel’s Story and the Davidic Royal Line?

Question 3087.

The book of Ruth is only four chapters long, a quiet rural story of famine, bereavement, gleaning, and a wedding, set in the lawless era of the judges. You could read it in fifteen minutes and enjoy it purely as one of literature’s finest short narratives. But the genealogy at its close, running from Perez through Boaz to “Jesse fathered David” (Ruth 4:18-22), announces that something far larger has been going on. This little story carries the royal bloodline of Israel, and through it the ancestry of the Messiah Himself. Let me show you why Ruth matters so much.

A Light in the Days of the Judges

The opening verse dates the story “in the days when the judges ruled” (Ruth 1:1), and anyone who has read Judges knows what that means: an age when “everyone did what was right in his own eyes” (Judges 21:25), an era of idolatry, violence, and moral freefall. Against that backdrop, the book of Ruth shines like a candle in a cellar. Here are ordinary people in a Bethlehem village keeping faith, keeping the law, and keeping covenant kindness alive while the nation unravels around them.

That setting is the first lesson. God’s redemptive programme did not pause during Israel’s worst centuries; it ran quietly through the faithfulness of unnoticed people. While the headlines belonged to warlords and civil war, the future of the monarchy, and of the world’s salvation, was being settled in a barley field.

Chesed: Covenant Kindness in Ordinary Clothes

The book of Ruth turns on the great Hebrew word chesed, covenant loyalty, steadfast love that goes beyond obligation. Naomi prays it over her daughters-in-law (Ruth 1:8); Boaz praises Ruth for it (Ruth 3:10); the whole narrative embodies it. Ruth’s own declaration is its most famous expression: “Where you go I will go… Your people shall be my people, and your God my God” (Ruth 1:16). A young Moabite widow binds herself to a destitute mother-in-law, a foreign people, and Israel’s God, with nothing to gain and every reason to turn back.

Notice that Ruth was a Moabitess, from a nation born of incest (Genesis 19), steeped in the worship of Chemosh, and formally excluded from the assembly of the LORD to the tenth generation (Deuteronomy 23:3). Yet by faith she took refuge “under the wings of the LORD, the God of Israel” (Ruth 2:12), and was received. Grace reaching a Gentile outsider and folding her into the covenant people: the book of Ruth preaches the Gospel centuries in advance.

The Kinsman Redeemer

At the heart of the plot stands the institution of the goel, the kinsman redeemer, from the Hebrew verb gaal, to redeem. Under the law, a near relative had the right to buy back a poor kinsman’s forfeited land (Leviticus 25:25) and, joined here with the duty of raising up offspring for a dead relative’s line, to marry the widow and preserve the family name. Boaz, “a worthy man” of Elimelech’s clan, does exactly this, publicly, legally, at the town gate, after graciously giving a nearer kinsman first refusal (Ruth 4:1-12).

Every element of the picture points beyond itself. The redeemer had to be a blood relative; he had to have the means to redeem; and he had to be willing. Jesus, our elder Brother who took our flesh and blood (Hebrews 2:14-15), possessed of infinite merit, and willing to pay “not with perishable things such as silver or gold, but with the precious blood of Christ” (1 Peter 1:18-19), is the Kinsman Redeemer to whom Boaz points. The book of Ruth gives us redemption with a human face before it gives us a royal genealogy.

The Book of Ruth and the Line to David and to Jesus

Then comes the ending that reframes everything. The child of Boaz and Ruth is Obed, “the father of Jesse, the father of David” (Ruth 4:17). The great-grandmother of Israel’s greatest king was a Moabite gleaner. When Matthew opens his Gospel with the genealogy of Jesus, he pointedly includes her: “Boaz the father of Obed by Ruth” (Matthew 1:5), one of four Gentile-connected women threaded into the Messiah’s ancestry, as I noted when writing on what Jesus’ genealogies tell us.

This is the significance of Ruth in Israel’s story: she stands in the direct channel of the promises. The line from Judah through Perez had been preserved through famine, emigration, and three funerals in Moab, and it ran on through her son to the throne of David, with which God would make an everlasting covenant, the Davidic covenant, promising a Son whose kingdom would have no end. Every time the New Testament calls Jesus Son of David, Ruth’s quiet faithfulness is standing somewhere in the background of the title.

Providence Without a Single Miracle

Here is a feature of the book of Ruth that repays a lifetime of meditation: it contains no miracle, no prophet, no voice from heaven. God is named constantly in blessing and prayer, but He never visibly intervenes. Instead we read that Ruth “happened to come to the part of the field belonging to Boaz” (Ruth 2:3), and the narrator’s gentle irony trusts us to see the hand behind the happenstance. Famine, migration, grief, the time of barley harvest, the order of kinsmen at the gate: every ordinary link is quietly forged by God.

Most of God’s people, most of the time, live in the book of Ruth rather than the book of Exodus: no parted seas, just providence working through choices, chances, and chores. Ruth teaches us to trust the God of the unspectacular, who was steering a famine-scattered family towards a manger in the very same village, Bethlehem, the house of bread, where the true Bread would one day be born (Micah 5:2).

Grace Was Already in the Family

Here is a detail that deepens the whole story. Matthew tells us that Boaz was himself the son of Rahab (Matthew 1:5), the Canaanite woman of Jericho who hid the spies and was spared with her household. If Matthew is giving us the immediate family line, then the man who welcomed a Moabite gleaner to his table had grown up with a Gentile mother who had been welcomed by grace before him. No wonder Boaz saw Ruth not as a foreign liability but as a woman of worth taking refuge under the wings of Israel’s God; he had watched that very grace at work in his own home. Kindness received has a way of becoming kindness shown.

Trace the genealogy further back and the pattern only strengthens. The line runs through Perez, born of Tamar in circumstances nobody would choose for a family history (Genesis 38), and on through Rahab and Ruth to David, and ultimately to the Messiah. The ancestry of Jesus is stocked with outsiders, scandals, and Gentiles, as though God were deliberately writing into the family tree the truth He would later announce from it: that grace is not embarrassed by origins, and that the door of the covenant stands open to faith from any nation.

Jewish tradition reads the book of Ruth at Shavuot, the Feast of Weeks, which Christians know as Pentecost, and it is hard to imagine a more fitting pairing. On the very feast when the story of a Gentile gathered into Israel at harvest time was read in the synagogues, the Spirit fell in Jerusalem and the harvest of the nations began (Acts 2). The book of Ruth had been quietly prophesying it for a thousand years: the Redeemer of Israel would be the Redeemer of the world, and His family would be drawn from every people under heaven. Naomi’s journey from emptiness to fullness, “the LORD has brought me back” (Ruth 1:21 with 4:14-17), becomes the journey of every soul the Redeemer brings home.

It is no wonder the Jewish canon places this little scroll among the festival readings and the church has treasured it ever since. In four short chapters the book of Ruth manages to teach covenant kindness, lawful redemption, the dignity of ordinary work, the welcome of the outsider, and the ancestry of the King of kings, all without a single wasted sentence. Scripture never spends four chapters on anything unimportant.

So, now what?

Take heart from the scale of this story. If God wove the redemption of the world through a widow’s loyalty, a farmer’s kindness, and a barley harvest, then no act of ordinary faithfulness in your life is wasted. The kindness you show this week may carry consequences you will only discover in glory; chesed always outlives the moment it is given.

And see yourself in Ruth: an outsider with no claim, received by grace, redeemed at cost, and given a future in the family of the King. Her Redeemer’s greater Son is yours for the trusting. Have you taken refuge under those wings?

“But Ruth 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.'” (Ruth 1:16, ESV)
