Gob in the Bible

And the Philistines went to war again with Israel; and David went down with his people, and while they were at Gob they had a fight with the Philistines:

And it came to pass after this, that there was again a battle with the Philistines, at Gob; then Sibbechai the Hushathite smote Saph, who was of the children of Raphah.

And there was again a battle at Gob with the Philistines; and Elhanan the son of Jaare-oregim, a Bethlehemite, smote Goliath the Gittite; now the shaft of his spear was like a weaver's beam.
