Book of Jubilees 34:11
And they dealt treacherously with him, and formed a plot against him to slay him, but changing their minds, they sold him to Ishmaelite merchants, and they brought him down into Egypt, and they sold him to Potiphar, the eunuch of Pharaoh, the chief of the cooks, priest of the city of 'Elew.
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.
