Book of Jubilees 30:17
For this reason I have commanded thee, saying: 'Testify this testimony to Israel: see how the Shechemites fared and their sons: how they were delivered into the hands of two sons of Jacob, and they slew them under tortures, and it was (reckoned) unto them for righteousness, and it is written down to them for righteousness.
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.
