There are 13 ancient history books that are mentioned and recommended by the Bible. The Ancient Book of Jasher is the only one of the 13 that still exists. It is referenced in Joshua 10:13; 2 Samuel 1:18; and 2 Timothy 3:8. This volume contains the entire 91 chapters plus a detailed analysis of the supposed discrepancies, cross-referenced historical accounts, and detailed charts for ease of use.
As with any history book there are typographical errors in the text but with three consecutive timelines running though the histories it is very easy to arrive at the exact dates of recorded events. It is not surprising that this ancient document confirms the Scripture and the chronology given in the Hebrew version of the Old Testament, once and for all settling the chronology differences between the Hebrew Old Testament and the Greek Septuagint.
