'Giant' in the Bible

And it came to pass after this, that there arose war at Gezer with the Philistines: then Sibbecai the Hushathite slew Sippai, of the sons of the giant; and they were subdued.

And there was again war at Gath, where was a man of great stature, whose fingers and toes were four and twenty, six on each hand , and six on each foot ; and he also was born unto the giant.

These were born unto the giant in Gath; and they fell by the hand of David, and by the hand of his servants.
