Gibborim (גּבּר גּבּור) is a Hebrew word that can be glossed "mightiest" which is an intensive for gabar (גּבר) that can be glossed "mighty". Many times it is used of people who are valiant, mighty, or of great stature. There is some confusion between Gibborim as a class of beings because of its use in Genesis 6:4. However, this passage describes the Nephilim as mighty (gibborim).
