Non-Canonical and Extra-Biblical Books and Letters Mentioned in the Bible

There are at least twenty-one extra-biblical books mentioned in the Bible. Each of these books may have been and probably were consulted by the Holy Spirit-inspired writers of the canonical books.  The Hebrews clearly had many other books than those included in the Bible. Some, such as the Book of Jasher, are mentioned in several verses.

"And the sun stood still, and the moon stayed, until the people had avenged themselves upon their enemies. Is not this written in the book of Jasher? So the sun stood still in the midst of heaven, and hasted not to go down about a whole day." Joshua 10:13

"(Also he bade them teach the children of Judah the use of the bow: behold, it is written in the book of Jasher.)" 2 Samuel 1:18

Jasher is not the name of a person. This is ספר הישר  Sefer (Book) Ha (the) Yashar (Upright, Correct, Just). The Latin Vulgate translates this as Book of the Just Ones while the Greek Septuagint translates the Hebrew as Book of the Upright.

This lost book was probably a collection of songs and poems about Hebrew battles and heroes. There are several books of Jasher which were composed much later than the biblical period and which are not the book mentioned in the Bible.

1. Sefer HaYashar: A collection of rabbinical theological writings which makes no claim to be the original book.
2. Pseudo-Jasher: ca 1625, a collection of Jewish legends.
3. Book of Jasher: 18th century. Claims to be a translation of the original book but most scholars consider this book to be an eighteenth century forgery.

Extrabiblical Evidences of Biblical Persons, Places, and/or Events: The Gezer Calendar

The Gezer Calendar is a tenth century BC/BCE (possibly 925 BC/BCE) fragment of an inscribed limestone  plate.  It was found in the ruins of the Canaanite city of Gezer (Tell el-Jazari).  The inscription is one of the earliest known examples of a text written in ancient Hebrew script.  It consists of seven lines of text and was discovered in 1908 by R.A.S. Macalister (see the bibliography below).  The Hebrew name, Abijah, appears in the text.

The calendar describes the crops planted, tended, and harvested in various months.  The purpose of the calendar is unknown, but some have suggested that it may have been used for taxation purposes.

The limestone tablet is housed in the Museum of the Ancient Orient in Istanbul, Turkey. The Jewish Virtual Library gives these bibliographical listings for the Gezer Calendar:

Biblical mentions of Gezer: Joshua 10:1-34, 12:12, 16:3-10, 21:21; 1 Chronicles 6:67, 7:28, 14:6, 20:4; Judges 1:29; 2 Samuel 5:25; 1 Kings 9:15-17.  Gezer is not mentioned in the New Testament.  During that period it was known as Gazara.

The Book of the Wars of the Lord

The Book of the Wars of the Lord is one of several otherwise unknown works mentioned in the Bible.  Gil Student, a Jewish scholar, in "On the Authorship of the Torah," at http://www.aishdas.org/toratemet/en_torah.html , says "... we have seen the talmudic and midrashic evidence that the forefathers, including Moshe, wrote books other than the Torah that were maintained and studied.  However, there is also much internal evidence that there were other books written."  The Book of the Wars of the Lord, quoted in Numbers 21:14-15, would be one of those books.

No one knows exactly what this book was but there have been many educated guesses: a collection of victory songs or poems; a book of Hebrew/ Israelite military history; another name for The Book of Jasher (mentioned in Joshua 10:13 and 2 Samuel 1:18); a collection of sacred poems; and a military instruction manual written by Moses for use by Joshua.

Non-canonical books such as The Wars of the Lord are mentioned in both the Old and New Testaments and Paul even quoted pagan poets to make his points.
