Q. Joshua 10:13 speaks of the book of Jasher. Please comment on what this is, and what is the significance of it.
“So the sun stood still, and the moon stopped, Until the nation avenged themselves of their enemies. Is it not written in the book of Jashar? And the sun stopped in the middle of the sky and did not hasten to go down for about a whole day.”
The traditional Jewish-Rabbinical teaching on this subject is divided. There are some who assert that this is a reference to the book of Genesis, others to the book of Deuteronomy, and still others who say it is a reference to the book of Judges. The Targum interprets it as the book of Law, another group of Jewish scholars says it is the book of the law of Moses.
However there are others who argue that the book of Jasher was a public register, or annals, in which memorable events were written, as they happened in different ages by different persons. Josephus (the 1st century Jewish historian) mentions an “archive” laid up in the temple which records significant events of the past. This may have been what is referenced here.
There are a number of references in the Scriptures to writings which were known by the original recipients of the Scriptures, but were known to be uninspired.
For example – Acts 17:28
“for in Him we live and move and exist, as even some of your own poets have said, ‘For we also are His children.'”
