'Gates' in the Bible

At dusk, when it was time to close the city gates, the men left. I don't know where the men went. Go after them quickly, and you might overtake them."

Then Joshua made everyone take the following oath at that time. He said: "Cursed in the presence of the LORD is the man who restores and rebuilds this city of Jericho! He will lay its foundation at the cost of his firstborn, and at the cost of his youngest he will set up its gates."

The men of Ai killed about 36 of them, pursuing them outside the city gates as far as Shebarim, killing them as they descended. As a result, the army became terrified and lost their confidence.
