'Gate' in the Bible

It happened about the time of the shutting of the gate, when it was dark, that the men went out. Where the men went, I don't know. Pursue them quickly; for you will overtake them."

The men pursued them the way to the Jordan to the fords: and as soon as those who pursued them had gone out, they shut the gate.

The men of Ai struck about thirty-six men of them, and they chased them from before the gate even to Shebarim, and struck them at the descent. The hearts of the people melted, and became like water.

He hanged the king of Ai on a tree until the evening, and at the sundown Joshua commanded, and they took his body down from the tree, and threw it at the entrance of the gate of the city, and raised a great heap of stones on it that remains to this day.

He shall flee to one of those cities, and shall stand at the entrance of the gate of the city, and declare his cause in the ears of the elders of that city. They shall take him into the city with them, and give him a place, that he may live among them.
