Where the manuscripts differ · Revelation 22:19
"Book of life" or "tree of life" — and the missing last page
The KJV's "book of life" at the very end of Revelation is not found in any Greek manuscript; it entered the printed Bible because Erasmus's only copy of Revelation was missing its final leaves and he translated the ending back from Latin.
This one has a story, and the story is the evidence. In 1516 the Dutch scholar Erasmus rushed the first printed Greek New Testament into press. For most of the New Testament he had several manuscripts to work from. For Revelation he had one — a medieval copy lent to him by the scholar Johann Reuchlin — and it was damaged. The final portion of the book was missing.
Erasmus did not have time to find another manuscript. So he did the only thing available to a man on a printer's deadline: he took the Latin Vulgate, which he knew intimately, and translated the missing verses back into Greek himself. He said so; this was not a secret. Those verses went into print as Greek text, and from there into the editions the King James translators used a century later.
The result is a handful of readings at the end of Revelation that no Greek manuscript anywhere contains, because they were composed in the sixteenth century by a scholar reconstructing a page he did not have. "Book of life" in verse 19 is the most visible of them. The Latin read *libro vitae* — book of life — and Erasmus rendered it faithfully. Every Greek manuscript of Revelation reads "tree of life."
What the manuscripts actually show
| Witness | Date | What it reads here |
|---|---|---|
| The Greek manuscripts of Revelation | 4th–15th centuries, all of them | "the tree of life" — without known exception in Greek. |
| The Latin Vulgate tradition | 4th century onward | "the book of life" — a Latin variation that never had Greek support. |
| Erasmus's printed Greek New Testament of 1516 | 1516 | "the book of life," retranslated by Erasmus from the Latin because his single Greek manuscript of Revelation lacked its closing leaves. |
| The immediate context, in every witness | All periods | Verse 19 goes on to say "and out of the holy city" — a pairing with the tree standing in the city of Revelation 22:2, which is what makes "tree" the reading the sentence is built around. |
The case each way
That it belongs in the text
The traditional English reading has four centuries of pulpit use behind it, and "book of life" is a thoroughly biblical phrase.
The Latin reading is genuinely ancient — this is not something Erasmus invented, but something he inherited from a Latin tradition going back many centuries.
That it came later
There is no Greek manuscript evidence for it. Not a weak reading — an absent one. This is why the case is settled rather than merely majority.
Its route into the English Bible is documented step by step, including Erasmus's own acknowledgment of what he did.
"Tree of life" is what the chapter is about. The tree stands in the middle of the street of the city in verse 2; verse 14 blesses those who have right to the tree of life and may enter the city. Verse 19's warning is the exact reversal of verse 14's blessing — losing the tree and the city — and that symmetry only works with "tree."
