Hear now, my sons, and I will uncover your eyes that you may see and understand the works of God, that you may choose that which pleases Him and reject that which He hates, that you may walk perfectly in all His ways and not follow after thoughts of the guilty inclination and after eyes of lust. For through them, great men have gone astray and mighty heroes have stumbled from former times till now. Because they walked in the stubbornness of their heart the Heavenly Watchers fell; they were caught because they did not keep the commandments of God. And their sons also fell who were tall as cedar trees and whose bodies were like mountains. All flesh on dry land perished; they were as though they had never been because they did their own will and did not keep the commandment of their Maker so that His wrath was kindled against them.

Flee, therefore, fornication, my children, and command your wives and your daughters, that they adorn not their heads and faces to deceive the mind: because every woman who useth these wiles hath been reserved for eternal punishment. For thus they allured the Watchers who were before the flood; for as these continually beheld them, they lusted after them, and they conceived the act in their mind; for they changed themselves into the shape of men, and appeared to them when they were with their husbands. And the women lusting in their minds after their forms, gave birth to giants, for the Watchers appeared to them as reaching even unto heaven.
