Nephilim
The Nephilim were a race of giants mentioned in the context of the sons of God marrying human women before the flood and later encountered by the Israelite spies in Canaan.
From Easton's Bible Dictionary
(Gen. 6:4; Num. 13:33, R.V.), giants, the Hebrew word left untranslated by the Revisers, the name of one of the Canaanitish tribes. The Revisers have, however, translated the Hebrew gibborim, in Gen. 6:4, "mighty men."
