Book of Jubilees 50:8
And the man that does any work on it shall die: whoever desecrates that day, whoever lies with (his) wife, or whoever says he will do something on it, that he will set out on a journey thereon in regard to any buying or selling: and whoever draws water thereon which he had not prepared for himself on the sixth day, and whoever takes up any burden to carry it out of his tent or out of his house shall die.
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.
