The International Nazarene Beit Din has made history today:
CANONICITY OF THE BOOK OF JASHER
Passed by the International Nazarene Beit Din
We the International Nazarene Beit Din do hereby declare Book of Jasher to be
part of the Nazarene Canon.
We have no hesitation in pronouncing this book to be a work of Divine
inspiration, great antiquity and interest, and a book that is entitled to a
great circulation among those who take pleasure in studying the Word of YHWH.
We declare that this book is profitable for teaching (doctrine) and
for reproof and for correction and for instruction in righteousness. While we
pronounce this book to be part of the official canon of the Assembly, we do
allow that a person who does not accept the canonicity of this book may still
personally be in good standing with the Assembly.
While the Beit Din recognizes the canonical status of the Book of Jasher in
general, there is currently only one Hebrew witness to the text and it dates
only to 1625 CE. To the extent that the current text reflects the original book
cited in the Tanak (Josh. 10:13 & 2Sam. 1:18) it is to be regarded as canon.
