Who, when, where
Ruth is anonymous. The Talmud names Samuel as the author, which fits the closing genealogy ending in David but is impossible to confirm. The events are set "in the days when the judges judged," roughly 1100 BC, the same period 1 Samuel opens in. Most modern scholars place the book's final form somewhere between the early monarchy (when David's lineage mattered politically) and the post-exilic period (when questions about foreign wives were live, especially under Ezra). The story moves between two settings: Moab, east of the Dead Sea, where Naomi's family emigrates during a famine; and Bethlehem in Judah, where Naomi and Ruth come home empty and where the harvest fields, the threshing floor, and finally the city gate run the action.
Where in history
Period of the Judges
Set "in the days when the judges judged"
- 1100 BC
Naomi's family moves to Moab during a famine
The book opens here. Roughly the same generation as Samson in the south and Samuel's birth at Shiloh.
- 1090 BC
Ruth returns to Bethlehem with Naomi; marries Boaz
The central action of chapters 2-4. The barley harvest dates this to early spring.
- 1085 BC
Obed born to Ruth and Boaz
Obed's grandson David will be born in this same town about 75 years later.
- 1010 BC
David becomes king of Judah
Ruth's great-grandson. The book's closing genealogy points here.
The amber span: Ruth: a Moabite great-grandmother for David.
The big idea
A Judahite family runs from famine into Moab, loses the husbands, and comes home with only two widows left. Naomi is bitter; her Moabite daughter-in-law Ruth refuses to leave her. Ruth gleans grain in a field that turns out to belong to Boaz, a relative of Naomi's late husband. Boaz notices her, protects her, and feeds her. Naomi sees a kinsman-redeemer in the offing and tells Ruth to go to the threshing floor at night. Boaz takes the legal step at the city gate, marries Ruth, and they have a son named Obed. The book closes with a four-verse genealogy: Obed begat Jesse, Jesse begat David. A Moabite woman who chose the God of Israel becomes David's great-grandmother.
Why this book still matters
Ruth is the bridge from the judges to David. The four-chapter story explains how a king from Bethlehem (David, and a thousand years later Jesus) has a Moabite in his family tree. Matthew opens the New Testament with a genealogy that names four women, all with complicated stories, and Ruth is one of them (Matthew 1:5). The book also stretches Israel's definition of covenant: the famous line Ruth says to Naomi ("whither thou goest, I will go ... thy people shall be my people, and thy God my God") gets used at conversions and weddings to this day. The Hebrew word *hesed*, loyal love that goes beyond what is owed, runs through the book and is what makes Boaz, Ruth, and Naomi recognizable to each other.
Ruth 4:17, 22
“And they called his name Obed: he is the father of Jesse, the father of David ... and Obed begat Jesse, and Jesse begat David.”
Matthew 1:5
"And Salmon begat Booz of Rachab; and Booz begat Obed of Ruth; and Obed begat Jesse; and Jesse begat David the king." Matthew opens the New Testament with a genealogy that names Ruth among the four women in Jesus' line.
Honest about what's debated
Three honest questions readers still ask. First, when was it written? Some place it in the early monarchy as a defense of David's mixed ancestry; others place it post-exile as a quiet counter to the policy of expelling foreign wives in Ezra 10. The text itself doesn't argue either case. Second, what actually happens on the threshing floor in chapter 3? "Uncovering the feet" can be a euphemism for more, and Hebrew commentators have read it both ways for centuries; the text is deliberately discreet. Third, who is the unnamed nearer kinsman in chapter 4? He has the first right to redeem Naomi's field but balks when he learns Ruth comes with it. The book never names him, which is striking given how careful it is with every other name.
Ruth is four short chapters. You can read the whole book in twenty minutes.
