Gob

Gob (also called Gezer in the parallel account of 1 Chronicles 20:4) was the site of two of the four duels between David's mighty men and the giant descendants of the Anakim who survived in the Philistine cities. There Sibbecai the Hushathite struck down Saph (also called Sippai), one of the descendants of the giants; and there Elhanan son of Jaare-oregim the Bethlehemite killed the brother of Goliath the Gittite, whose spear shaft was like a weaver's beam (2 Samuel 21:18-19, 1 Chronicles 20:4). The four giant-slayings catalogued in 2 Samuel 21:15-22 mark the final extermination of the Anakim remnant that had survived in the Philistine pentapolis after Joshua's campaign in the hill country generations earlier (Joshua 11:21-22). The location of Gob is uncertain; some scholars identify it with Gezer (per the Chronicles parallel) or with a site in the Shephelah near Gath.
