New Defender's Study Bible Notes
1:18 book of Jasher. The book of Jasher is also referenced in support of the amazing long day of Joshua (Joshua 10:13). This book was considered lost for many centuries, but a fascinating volume purporting to be the lost book of Jasher surfaced in modern times, and it does contain the two passages noted in the Bible. Its authenticity is very doubtful, but when and how it was written are unknown.
