This is what I am seeing for nephelim:-
Genesis 6:4
giants — The term in Hebrew implies not so much the idea of great stature as of reckless ferocity, impious and daring characters, who spread devastation and carnage far and wide. (Jamison, Fawcett, Brown)
H5303
nephi^yl nephil
nef-eel', nef-eel'
From H5307; properly, a feller, that is, a bully or tyrant: - giant.
Total KJV occurrences: 3
They would be the sons of men (heathens) rather than the sons of God (believers).
