'Giants' in the Bible

Then Ishbi-benob, who was among the descendants of the giant, the weight of whose spear was three hundred shekels (six pounds) of bronze, was armed with a new sword, and he intended to kill David.

There was war at Gath again, where there was a man of great stature who had six fingers on each hand and six toes on each foot, twenty-four in number; he also was a descendant of the giants.
