The chapter 'Qayin's Jealousy over the Sisters' moves the narrative into the first generation born outside the Garden.

Qayin, Hevel, Luluwa, and Aklia grow within a household still carrying the memory of Eden and the Cave.

Jealousy over offering, honor, and marriage arrangements develops inside Qayin until he begins to treat his brother as an obstacle.

Satan feeds the jealousy, but the text does not remove Qayin's agency: he plans, lures, and strikes Hevel.

The first human death by violence shatters the household, and judgment follows Qayin's bloodshed.
