They are often characterized as giants or mighty men, embodying both human and divine qualities. The term is derived from the Hebrew Bible and has generated various interpretations concerning their nature, origins, and significance. Nephilims are often associated with themes of fallen angelic beings, corruption, and the pre-flood world. Their portrayal raises questions about the interplay between divine and human realms, sparking theological debates throughout history concerning ethics, power, and morality.
