'Gates' in the Bible

The men of Israel and Judah got up with a shout and pursued the Philistines as far as the entrance to the valley and to the gates of Ekron. Wounded Philistines fell along the way to Shaaraim as far as Gath and Ekron.

It was reported to Saul that David had come to Keilah, and Saul said, "The LORD has delivered him into my hand because he has shut himself in by going into a town with double gates and bars."
