Book of Jubilees 49:9
And the man who is free from uncleanness, and does not come to observe it on occasion of its day, so as to bring an acceptable offering before the Lord, and to eat and to drink before the Lord on the day of its festival, that man who is clean and close at hand shall be cut off: because he offered not the oblation of the Lord in its appointed season, he shall take the guilt upon himself.
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.
