Book of Jasher

The lost book of Jasher referenced in Joshua and 2 Samuel. Read it with chapter navigation, full-text search and bookmarks.

Why we built it

Joshua commands the sun to stand still over Gibeon, and the verse says the event is written in the book of Jasher; 2 Samuel names the same book again. What survives under that name is a long retelling of Genesis to Judges, and readers usually meet it as a plain text file. This edition gives it the things a long text needs — a chapter index with opening lines, narration, search, and a commentary note beside each chapter so a reader can tell which parts are scripture, which are retelling, and where the two diverge.

How it works

The full Sefer haYashar is presented chapter by chapter, numbered verse by verse and listed in an index with its opening words, so a passage can be found by subject as well as by number.

A commentary note beside each chapter says what that chapter retells and where the retelling departs from the scriptural account — usually the first question a reader of Jasher brings to it. Narration, search and bookmarks work as they do in the other reading editions.

What it does

The full Sefer haYashar

Every chapter of the edition the book is usually read in, numbered verse by verse rather than delivered as one long page.

Chapter index

The whole book is listed by chapter with its opening words, so a passage is found by its subject as well as its number.

Narration

Audio for each chapter, started from the chapter header.

Commentary beside the text

A note on the chapter's place in the book sits alongside it — what it retells, and where the retelling differs.

Search and bookmarks

Search the text, and save a place to return to from your profile.

What it does not do

A limit named before you open the app is worth more than a feature list that never mentions one.

  • It presents one edition, the Sefer haYashar. It is not a critical edition and does not collate variants.
  • The text is English; no Hebrew original or interlinear is shown.
  • The commentary guides the reading rather than citing every claim academically.
