Most readers think the Bible holds every sacred text that ancient Israel ever wrote. But the Bible itself tells a different story. Its writers quote older scrolls by name, and many of those scrolls are now gone. The most famous of them is the Book of Jasher. It appears twice in the Hebrew Bible, each time at a turning point in Israel’s history. Then it disappears from sight.
So what was this book, and why did it vanish? Later writers tried to fill the gap, and some of them were honest while others were not. In this article we follow the trail from two short verses to a medieval storybook and a notorious English forgery. Along the way, we learn a lot about how the Bible took shape.
If you want the wider picture first, start with our guide to Exploring the Apocrypha: Forgotten Scriptures that Shaped Christian Thought. It shows that the Bible grew out of a much larger library.
Two Verses That Point to a Lost Library
Ancient Israel had writers, singers and record keepers long before anyone closed the Bible. Kings kept annals. Poets kept songs. Prophets left collections of their sayings. The biblical authors knew these works and quoted them freely.
In fact, the Hebrew Bible names more than a dozen sources that no longer exist. There is the Book of the Wars of the Lord in Numbers 21:14. Next come the Acts of Solomon in 1 Kings 11:41. There are the records of Nathan the prophet and Gad the seer in 1 Chronicles 29:29. Scholars call these the lost books of the Old Testament.
Among them, the Book of Jasher stands out. The Bible quotes it at two dramatic moments, and each quote is a piece of poetry. That detail matters, as we will see. It tells us what kind of book it was.
The Book of Jasher in Joshua’s Long Day
The first quote comes in Joshua 10. Five Amorite kings had joined forces against the city of Gibeon, which had made peace with Israel. Joshua marched all night to defend his new allies. Then the Lord threw the enemy into panic, and great hailstones fell on them as they fled.
At this point Joshua spoke a short poem. He asked the sun to stand still over Gibeon and the moon over the valley of Aijalon. The narrator then adds a striking line. He asks, “Is not this written in the book of Jasher?” You can read the whole chapter in Joshua 10 on BibleGateway.
Notice what the writer is doing here. He does not use the Book of Jasher as his main source. Instead, he points to it as a second witness. His readers knew the book, and he invites them to check the poem for themselves. So the scroll must have been well known and widely trusted at the time.
David’s Lament and the Song of the Bow
The second quote comes in 2 Samuel 1. King Saul and his son Jonathan had just died in battle on Mount Gilboa. David was their rival, yet he mourned them deeply. He wrote one of the most moving poems in the whole Bible.
“How are the mighty fallen,” the lament says again and again. It praises Saul and Jonathan as swifter than eagles and stronger than lions. It ends with David’s grief for Jonathan, whose love was “wonderful” to him. Before the poem begins, the narrator says David taught it to the people of Judah. He then adds that it is “written in the book of Jasher.” The passage is in 2 Samuel 1 on BibleGateway.
So the two quotes share a pattern. Both are songs, and both honour heroes in war. One celebrates a victory, while the other mourns a defeat. Together they suggest that the scroll was a national songbook. It kept the poems that Israel sang about its leaders and its battles.
What the Name Book of Jasher Really Means
The name “Jasher” is not the name of an author. It comes from the Hebrew word yashar, which means “upright,” “straight” or “just.” So the Book of Jasher is best translated as “the Book of the Upright.”
But who were the upright? Most likely they were the heroes of Israel’s past. The book seems to have gathered songs in their honour. Some scholars think “the upright” was even a poetic name for Israel itself. Either way, the title fits a collection of heroic poems.
The old translators tried to explain the name too. The Greek version of Joshua simply leaves the line out. In 2 Samuel, however, the Greek calls it the “book of the upright one.” Meanwhile the Latin Vulgate renders it as the “book of the just.” These choices show that early readers saw the title as a description, not a personal name.
Songbooks like this often grew over time. Singers added new poems as new heroes arose. That would explain why the scroll covers events from Joshua to David, a span of several centuries. For a sense of how such writings fit together, see our Apocryphal Books Timeline.
A Third Trace in the Greek Bible
There may be a third quote hiding in plain sight. It sits in the story of Solomon’s temple, in 1 Kings 8. When the builders finished the temple, Solomon spoke a short poem about the Lord dwelling in thick darkness.
In the Hebrew text, this poem has no source note. But the Greek translation adds one. It says the poem is “written in the book of the song.” In Hebrew, “song” and “Jasher” use the same three letters in a different order. So many scholars think a copyist simply swapped two letters. If they are right, the Greek has preserved a third quote from the same songbook.
This clue fits the others well. Once again, the quote is a poem. Once again, it marks a great moment in Israel’s story. You will find most of the details in the Wikipedia article on the Book of Jasher, which also lists the later books that borrowed the name.
The Medieval Book of Jasher and Its Legends
The original scroll was lost, yet its name lived on. In the Middle Ages, a Jewish writer produced a long Hebrew work called Sefer haYashar. It retells the story of the Torah from Adam to the time of the Judges. It fills the gaps with colourful legends drawn from rabbinic tradition.
This medieval Book of Jasher is a lively read. For example, it describes Jacob’s sons fighting great wars against the kings around Shechem. It also tells how Moses fled Egypt and ruled as king of Cush for forty years. It adds stories about Enoch and the early patriarchs as well. Those tales echo the themes in our study of The Legacy of Enoch in Jewish and Christian Traditions.
The oldest printed edition appeared in Venice in 1625. Its preface claimed the book came from an ancient scroll found in the ruins of Jerusalem. However, scholars date the Hebrew to the eleventh or twelfth century. Its language and ideas belong to the Middle Ages, not to the time of Joshua. You can read more about it in the Wikipedia entry on Sefer haYashar.
An English translation came out in New York in 1840. It was later reprinted in Salt Lake City, and many readers today meet this version first. It is a fine example of Jewish storytelling. Still, it is not the scroll that Joshua and Samuel quoted. For another late book that retells Genesis in its own way, see our look at The Book of Jubilees Calendar.
Jacob Ilive and the Alcuin Forgery
A much stranger version appeared in England in 1751. A London printer named Jacob Ilive published what he called the true Book of Jasher. He said it had been translated into English by Alcuin, the famous scholar from the court of Charlemagne.
According to the story, Alcuin travelled to Persia and found the scroll in the city of Gazna. He then spent years putting it into English. Yet the book copies the style of the King James Bible of 1611. No eighth-century scholar could have written that way. In addition, the book carried a note of praise from John Wycliffe, who lived five hundred years after Alcuin.
Critics saw through the hoax almost at once. The text also had an agenda. Ilive was a radical thinker who distrusted miracles and the clergy. His Jasher quietly explains away some wonders of the Old Testament. It paints Moses as a harsh ruler and the priests as schemers.
Ilive’s career did not end well. In 1756 he was jailed for three years for a different pamphlet, one that attacked the sermons of the Bishop of London. His forgery, however, outlived him. A Bristol printer brought it out again in 1829, and copies still circulate today. You can trace his odd life in the Wikipedia biography of Jacob Ilive.
Why the Book of Jasher Never Reached the Canon
If the Bible quotes this book, why is it not in the Bible? The answer has two parts.
First, the book may not have survived. Many scrolls were lost when Babylon destroyed Jerusalem in 586 BC. When the exiles came home, their scribes worked with what remained. A songbook that burned with the temple could not be copied again. That alone may explain its absence.
Second, the scribes had a clear idea of scripture. They kept books they saw as prophetic or tied to the covenant. A collection of war songs was a treasured record, but it was not the same as the law or the prophets. So the biblical writers kept the best poems inside their own books, and the source itself faded away. For more on this process, read our study Why Were the Apocryphal Books Removed From the Bible?
In the end, the lost Book of Jasher reminds us that the Bible is a selection. Behind it stood a rich world of songs, records and stories. Discoveries like the Dead Sea Scrolls keep showing how large that world was. We may never hold the scroll of the upright in our hands. Yet its songs still speak through Joshua’s long day and David’s lament, and that is a legacy worth knowing.
