What This Chapter Is About
Jacob's sons tend flocks near Shechem. Joseph is sent to check on his brothers. They conspire against him, sell him to Midianite merchants bound for Egypt. The brothers dip his coat in goat blood. Jubilees dates the arrival of the bloody coat to the tenth of the seventh month — the Day of Atonement — creating an etiology for that fast day.
What Makes This Chapter Remarkable
Jubilees introduces the tenth of the seventh month as the date Joseph's blood-stained coat was brought to Jacob, giving etiological significance to this day of mourning.
Translation Friction
The insertion of Mastema as instigator partially shifts blame from the brothers to a demonic agent.
