The Nephilim, the product of the sons of god mingling with the daughters of Adam, the great Biblical giants, “the fallen ones,” the Rephaim, “the dead ones”—these descriptions are all applied to one group of characters found within the Hebrew Bible. Who are the Nephilim? From where do the “heroes of old, the men of renown” come?
Genesis 6:1–4 tells the readers that the Nephilim, which means “fallen ones” when translated into English, were the product of copulation between the divine beings (lit. sons of god) and human women (lit. daughters of Adam). The Nephilim are known as great warriors and Biblical giants (see Ezekiel 32:27 and Numbers 13:33).
It was once claimed that the mating of the sons of god and the daughters of Adam that resulted in the Nephilim caused the flood, and this caused the Nephilim to have a negative reputation. This was believed because the next verse (Genesis 6:5) is the introduction to the flood narrative and because their name means “fallen ones.” It is unlikely that this interpretation is correct because Genesis 6:4 presents nothing but praise for the Nephilim and no criticism is present. In addition, the name “fallen ones” is likely a reference to their divine paternity transforming—falling—into the human condition, albeit an almost superhuman condition.
