'Giant' in the Bible

It happened after this, that there arose war at Gezer with the Philistines: then Sibbecai the Hushathite killed Sippai, of the sons of the giant; and they were subdued.

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

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