'Descendant' in the Bible

After this, there was war again with the Philistines at Gob (Gezer). At that time Sibbecai the Hushathite killed Saph (Sippai), who was among the descendants of the giant.

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.
