The Nephilim /ˈnɛfɨˌlɪm/ were offspring of the sons of God and the daughters of men before the Deluge according to Genesis 6:4; the name is also used in reference to giants who inhabited Canaan at the time of the Israelite conquest of Canaan according to Numbers 13:33. A similar biblical Hebrew word with different vowel-sounds is used in Ezekiel 32:27 to refer to dead Philistine warriors. Giants Nephilim as heavenly beings who came to earth and had sexual intercourse with women the Nephilim DNA to be an anecdote of a superhuman race.
Some Bible Scholars have argued against this view, citing Jesus’s statement that angels do not marry. Others believe that Jesus was only referring to angels in heaven.
Evidence cited in favor of the fallen angels interpretation includes the fact that the phrase the sons of God (Hebrew, בְּנֵי הָֽאֱלֹהִים; literally sons of the gods) is used twice outside of Genesis chapter 6, in the Book of Job (1:6 and 2:1) where the phrase explicitly references angels. The Septuagint’s translation of Genesis 6:2 renders this phrase as the angels of God.
