Book of Jubilees 2:29
Declare and say to the children of Israel the law of this day both that they should keep Sabbath thereon, and that they should not forsake it in the error of their hearts; (and) that it is not lawful to do any work thereon which is unseemly, to do thereon their own pleasure, and that they should not prepare thereon anything to be eaten or drunk, and (that it is not lawful) to draw water, or bring in or take out thereon through their gates any burden, which they had not prepared for themselves on the sixth day in their dwellings.
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.
