'Gates' in the Bible

And the men of Israel and of Judah arose, and shouted, and pursued the Philistines, until thou comest to Gai, and to the gates of Ekron. And the wounded of the Philistines fell down by the way to Shaaraim, even unto Gath, and unto Ekron.

And it was told Saul that David was come to Keilah. And Saul said, God hath delivered him into my hand; for he is shut in, by entering into a town that hath gates and bars.
