The term "watchers" is also mentioned in the Book of Genesis. The term "Nephilim" is mentioned in the Book of Genesis, and is associated with a group of ancient giants who were said to have lived in the pre-Flood world.
In the Book of Genesis, it is written that the "Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of men, and they bore children to them. Those were the mighty men who were of old, men of renown" (Genesis 6:4). This passage has been interpreted in various ways, with some scholars suggesting that the "sons of God" may refer to fallen angels or divine beings who mated with human women, while others suggest that they may refer to the descendants of Seth (a son of Adam and Eve) who intermarried with the descendants of Cain (another son of Adam and Eve).
The Book of Enoch, a Jewish text from the Second Temple period, describes the Nephilim as the offspring of the "sons of God" and the "daughters of men," and identifies the "sons of God" as a group of fallen angels known as the Watchers. According to the Book of Enoch, the Watchers were sent to earth to teach humans about civilization, but they became corrupt and taught humans forbidden knowledge, including the use of weapons and magic.
The Book of Jubilees, another Jewish text from the Second Temple period, also associates the Nephilim with the Watchers. According to Jubilees, the Watchers descended to earth in the days of Jared (a pre-Flood patriarch), and they taught humans various forms of knowledge, including astrology, enchantments, and the use of metals. They also began to lust after human women and took them as wives, which resulted in the birth of the Nephilim.
In summary, the Bible associates the Nephilim with a group of ancient giants who lived in the pre-Flood world, and the term "watchers" is mentioned in association with a group of fallen angels or divine beings who may have mated with human women and produced the Nephilim, according to some interpretations of the text.
