What happened on Mount Hermon?

On Mount Hermon two hundred Watchers descended in the days of Jared and swore a solemn oath binding themselves to take human wives and beget children. Their leader Semjaza feared he alone would bear the penalty if the others abandoned the plan, so the entire company joined in mutual imprecations upon the summit, ensuring none could later shift blame (1 Enoch 6; Book of Enoch 6).

They named the mountain Hermon after the curse they invoked, turning an ordinary peak into the lasting symbol of their rebellion. This organized descent - a full company of two hundred - breached the boundary between heaven and earth, introducing forbidden knowledge, the birth of the Nephilim, and the violence that would ultimately require the Flood (Geography - Geography: Mount Hermon; Timeline Facts - fall-of-the-watchers).

The oath itself parodied sacred covenant-making, using holy forms for a profane purpose and marking the mountain forever as the place where celestial beings first chose to corrupt the natural order (Covenant Facts - watchers-oath; Verse Notes - The Book of Enoch 6:1-8).
