'Gates' in the Bible

The men of Israel and Judah arose and shouted and pursued the Philistines as far as the valley, and to the gates of Ekron. And the slain Philistines lay along the way to Shaaraim, even to Gath and Ekron.

When it was told Saul that David had come to Keilah, Saul said, “God has delivered him into my hand, for he shut himself in by entering a city with double gates and bars.”
