'Giants' in the Bible

Later, the Three Warriors went down to David's hideout at the cave of Adullam when the Philistine army was camping in the valley of giants.

After this, a war broke out with the Philistines at Gezer. At that time Sibbecai the Hushathite killed Sippai, a descendant of the giants, and the Philistines were subdued.

Again there was war at Gath, where there was a man of great stature who had twenty-four fingers and toes, six fingers on each hand and six toes on each foot; and he also was descended from the giants.

These descendants from the giants in Gath died at the hands of David and his servants.
