Azaz’el is mentioned as teaching the people about weapons, war, make-up, jewelry, and alchemy. His teachings, along with those of other sinning Watchers, were responsible for corrupting the whole Earth. The Watchers took wives, and had children by them. The children of the Watchers were giants who consumed all of the food, and then turned on the people and animals. An angel took them away from the humans and forced them to fight and eventually kill each other, but their spirits remained bound to the Earth.
