Who wrote the book of Ruth?
Jewish tradition credits Samuel as the author of Ruth, writing between roughly 1010–990 BC — after David became king but before Solomon’s reign. Some scholars, however, argue a post-exilic author penned it centuries later as a theological statement about welcoming outsiders, using David’s lineage to lend the story credibility.
Who Wrote the Bible? — Series 4
A love story across enemy lines — and the great-grandmother of a king. Ruth is not playing around.
Wait — who is Ruth?
Before we get into authorship, let’s set the scene. Ruth is a Moabite woman who ends up marrying an Israelite man. After he dies, she refuses to leave his mother Naomi and travels with her back to Israel. There she meets Boaz — and the rest, as they say, is history. Literally.
Ruth’s place in the family tree
Ruth + Boaz → Obed → Jesse → King David → … → Jesus
That family tree is not a small detail. Ruth — a foreign woman from a nation Israel had serious beef with — ends up in the direct bloodline of King David, and by extension, Jesus. The book is only four chapters long, but its reach across the rest of the Bible is enormous.
Why was Ruth and Boaz such a big deal?
Because Moab and Israel did not get along. At all. The origin story of Moab is genuinely one of the most dramatic in the Bible — after the destruction of Sodom and Gomorrah, Lot’s daughters got their father drunk and, well, nine months later the Moabite nation was born. The relationship between Israel and Moab never really recovered from that origin story. There was conflict, exclusion, and centuries of side-eye between the two peoples. Serious beef.
So Ruth — a Moabite woman — choosing Israel, and an Israelite man choosing her back? That would be trending content by today’s standards. It’s a story about loyalty, love, and crossing boundaries that society said shouldn’t be crossed.
The Hebrew word for Ruth’s loyalty to Naomi — “hesed” — is the same word used for God’s faithful love throughout the Old Testament.
So who wrote it?
Jewish tradition points to Samuel — the same figure we discussed in the Judges instalment. The internal clues from the text are what point us there:
| Ruth 1:1 | Ruth 4:17-22 |
| The book opens “in the days when the judges ruled” — past tense. The author is looking back at the judge era, meaning they’re writing after it ended, i.e. after kings came on the scene around 1050 BC. Written after the monarchy began. | The book ends with a genealogy that goes all the way to King David — but stops there. Solomon, David’s son, isn’t mentioned. Since Solomon’s reign began around 970 BC, this places the writing between roughly 1010 and 990 BC. Written after David became king, before Solomon’s reign. |
That window lines up neatly with Samuel’s lifetime. He anointed David as king, he was active right at the close of the judge era, and he had every reason to document a story that legitimised David’s lineage — including a Moabite great-grandmother who embodied the kind of faithfulness Samuel valued.
But not everyone buys it
Some scholars push the authorship much later — to the post-exilic period, around the late 6th or 5th century BC. Their argument hinges on a bigger question: is Ruth a historical account, or a carefully crafted story?
| Samuel wrote it (~1010–990 BC) | Post-exilic author (~500s BC) |
| Ruth is real history — David was real, so his family history is real. Samuel recorded it close to the events. | Ruth is a composed story, written to make a theological point about welcoming outsiders, using the David connection for credibility. |
The post-exilic theory argues the book was written as a counter-narrative to strict “Israel only” policies of the era — a way of saying, through story, that even King David had foreign blood. It’s a compelling read. But it requires treating the book as fiction, which not everyone is willing to do.
So — real history or compelling story?
We know King David existed. We know Moab existed. The real question is whether Ruth did too — and whether her story was preserved because it happened, or invented because it needed to be told.
Either way, a cross-cultural love story that ends up in the bloodline of the most important figure in the New Testament is worth paying attention to — regardless of who put it on paper.
History or story?
Does a Moabite-Israelite love story sound too good to be true, or exactly the kind of thing that was bound to happen?
