"They teach humans “magical medicines, incantations, the cutting of roots and about plants.” The origin of folk-medicine is therefore ascribed to these angelic beings"
"In addition to teaching humans in interpret a wide range of signs, they teach humans medicinal magic. The angel Azazel teaches humans metal-working, including making of ornaments and weapon making. Azazel also teaches them to make eye-shadow and other physical ornamentation. This may be a polemic against pagan practice of using make up in their religious ceremonies. Other angels teach the humans how to track the stars (astrology and divination) and the signs of the moon."

"Azazel, who is presumed to be a watcher, teaches man the use of swords, knives and warfare, much as the Watchers taught mankind the secrets of heaven, incarnations and sorcery.
Azazel also teaches mankind the use of paint, stones, and dyes, so that man can manipulate the world and alter it."
"The rest of the chapter tells us that the other Watchers taught mankind astrology, science, astronomy and that with their presence, men were destroyed, and their cries reached the heights of heaven."
