Book of Jubilees 23:16
And in that generation the sons shall convict their fathers and their elders of sin and unrighteousness, and of the words of their mouth and the great wickednesses which they perpetrate, and concerning their forsaking the covenant which the Lord made between them and Him, that they should observe and do all His commandments and His ordinances and all His laws, without departing either to the right hand or the left.
Background and history of Book of Jubilees, and issues with this book.
R. H. Charles, The Book of Jubilees, in The Apocrypha and Pseudepigrapha of the Old Testament, vol. 2 (Oxford: Clarendon Press, 1913). Public domain in the United States (published 1913). Charles died in 1931, so the book is in the public domain in the United Kingdom. The verse text is the Joshua Williams transcription at pseudepigrapha.com. Jubilees 1:8 and 1:9 are divided at the break in the 1902 Clarendon scan (archive.org bookofjubileesor00char), where verse 9 begins “For they will forget.” That scan also numbers the angel-of-the-presence sentence as 1:29. Editorial brackets in the translation are Charles’s.
